Description
Technical Field
The invention relates to the technical field of multiphase flow numerical simulation, in particular to a multiphase flow field initialization method, a device, equipment and a medium.
Background
Multiphase flow is an important branch of the field of fluid mechanics, and the term "phase" generally refers to the thermodynamic state of matter, generally divided into solid, liquid and gas phases. Compared with the single-phase flow problem, because multi-phase flow involves the combined action among multiple phases, the simulation complexity and the calculation difficulty of the multi-phase flow are extremely high, and the initialization of a multi-phase flow field is more complicated, which is a problem to be solved firstly. For single-phase streaming problems, the global domain is usually uniformly initialized directly using uniform incoming streams, and developers need only write a single function to cover almost all initialization possibilities. However, the initial field of the multiphase flow problem generally has the non-uniform characteristics of components and flow field parameters, and generally needs to be individually treated according to specific problems. Because developers cannot exhaust all possibilities in software, and users are strictly prohibited from accessing and modifying the main program source code, in order to ensure the source code security and simultaneously give users enough freedom to implement the initialization process for different multiphase flow problems, the following two strategies are generally adopted at present: the interpretation method is complex in realization and needs to write an interpreter manually by interpreting sentences input by a user one by one to realize corresponding functions, and meanwhile, the efficiency is greatly influenced for a calculation-intensive program such as computational fluid mechanics due to high interpretation time complexity; the compiling method is divided into a static link library and a dynamic link library, wherein the static link library and an implicit dynamic link library are required to be completed in the compiling and linking stage, and a compiling system compiles and links according to a header file and a library file of the dynamic library, namely the library is required to be added into the project of an application program, so that the prototype and the address of a called function are determined. For the static library, recompilation is required for each modification, which brings great inconvenience to the use of users. In conclusion, how to be more flexible and efficient in the process of initializing the multiphase flow field needs to be further solved.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The initial field of the multiphase flow problem generally has the non-uniform characteristics of components and flow field parameters, and generally needs to be treated independently according to specific problems. Because developers cannot exhaust all possibilities in software, and users are strictly prohibited from accessing and modifying the main program source code, in order to ensure the source code security and simultaneously give users enough freedom to implement the initialization process for different multiphase flow problems, the following two strategies are generally adopted at present: the interpretation method is complex in realization and needs to write an interpreter manually by interpreting sentences input by a user one by one to realize corresponding functions, and meanwhile, the efficiency is greatly influenced for a calculation-intensive program such as computational fluid mechanics due to high interpretation time complexity; the compiling method is divided into a static link library and a dynamic link library, wherein the static link library and an implicit dynamic link library are required to be completed in the compiling and linking stage, and a compiling system compiles and links according to a header file and a library file of the dynamic library, namely the library is required to be added into the project of an application program, so that a called function prototype and an address are determined. For a static library, recompilation is required for each modification, which brings great inconvenience to the use of users. Therefore, the multi-phase flow field initialization method provided by the application can be more flexible and efficient in the process of multi-phase flow field initialization.
The embodiment of the invention discloses a multiphase flow field initialization method, which comprises the following steps of:
step S11: and acquiring a target initialization function source code corresponding to the initialization requirement of the target multiphase flow field through a main program of the numerical simulation software and a preset interactive interface of the dynamic link library.
In this embodiment, the preset interactive interface is an interactive interface between a main program preset by a main program developer of the numerical simulation software and an external dynamic link library. Specifically, a user determines a target initialization function source code corresponding to an initialization requirement in advance according to the initialization requirement of a target multiphase flow field, and inputs the target initialization function source code from the preset interactive interface to obtain the target initialization function source code. Through the technical scheme, the target initialization function source code corresponding to the initialization requirement of the target multiphase flow field is obtained, so that the target dynamic link library is constructed on the basis of the target initialization function source code.
Step S12: and compiling the target initialization function source code by using a preset compiler based on the operating system operated by the numerical simulation software to obtain a target dynamic link library corresponding to the target initialization function source code, and then adding the information of the target dynamic link library into the configuration parameter file of the main program of the numerical simulation software.
In this embodiment, according to an operating system in which the numerical simulation software operates, the target initialization function source code is compiled by using a corresponding preset compiler, a target dynamic link library corresponding to the target initialization function source code is obtained, and information of the target dynamic link library is further added to a configuration parameter file of a main program of the numerical simulation software. According to the technical scheme, the target dynamic link library corresponding to the initialization requirement of the target multiphase flow field is obtained, and the information of the target dynamic link library is added in the configuration parameter file of the main program of the numerical simulation software, so that the target multiphase flow field can be initialized based on the information of the target dynamic link library when the running instruction of the multiphase flow solving program in the numerical simulation software is obtained subsequently.
Step S13: and acquiring an operation instruction of a multiphase flow solving program of the numerical simulation software, and initializing the target multiphase flow field based on the information of the target dynamic link library in the configuration parameter file.
In this embodiment, the operation instruction of the multiphase flow solver of the numerical simulation software is an instruction corresponding to the initialization requirement of the target multiphase flow field. Specifically, an operation instruction of a multiphase flow solving program sent by a user from a preset interface is obtained, and the target multiphase flow field is initialized based on target dynamic link library information in the configuration parameter file. According to the technical scheme, the target initialization function source code is compiled into the target dynamic link library through the preset compiler, the explicit dynamic link library is adopted to enable the operating system function to realize the operations of loading, unloading and the like of the dynamic link library, the function address and the error information can be flexibly called, and compared with the static link library and the implicit dynamic link library, the method is more flexible, and therefore the method is more efficient in multi-phase flow field initialization.
It can be seen that, when the multi-phase flow field is initialized, in this embodiment, first, a target initialization function code corresponding to an initialization requirement of a target multi-phase flow field is obtained through an interactive interface between a main program and a dynamic link library, and a preset compiler is further used to compile a target initialization function source code to obtain a target dynamic link library corresponding to the target initialization function source code, information of the target dynamic link library is added to a configuration parameter file of the main program of the numerical simulation software, and when a multi-phase flow solving program of the numerical simulation software is obtained and executed, the target multi-phase flow field is initialized based on the information of the target dynamic link library. Therefore, when the multi-phase flow field is initialized, the target initialization function source code is compiled into the target dynamic link library through the preset compiler, the explicit dynamic link library is adopted, the operation system function can realize the operations such as loading and unloading of the dynamic link library, the function address and the error information can be flexibly called, and compared with the static link library and the implicit dynamic link library, the method is more flexible, and therefore the method is more efficient when the multi-phase flow field is initialized. In conclusion, the multi-phase flow field initialization method is more flexible and efficient when a multi-phase flow field is initialized.
Referring to fig. 2, the embodiment of the present invention discloses a specific multiphase flow field initialization method, and compared with the previous embodiment, the present embodiment further describes and optimizes the technical solution.
Step S21: and acquiring a target initialization function source code corresponding to the initialization requirement of the target multiphase flow field through a main program of the numerical simulation software and a preset interactive interface of the dynamic link library.
In this embodiment, before obtaining a source code of a target initialization function corresponding to an initialization requirement of a target multiphase flow field through a main program of numerical simulation software and a preset interactive interface of a dynamic link library, the method further includes: and calling a corresponding system function based on an operating system environment operated by the numerical simulation software to construct a preset interactive interface of a main program of the numerical simulation software and a dynamic link library. Specifically, a developer of the main program calls a system function according to the running operating system environment to write an interface for interaction between the main program and an external library, and the system function under Windows is as follows:
HMODULE LoadLibraryA(LPCSTR lpLibFileName);
FARPROC GetProcAddress(HMODULE hModule, LPCSTR lpProcName);
the system functions under Linux are as follows:
void *dlopen(const char *file, int mode);
void *dlsym(void *handle, const char *name);
further, before obtaining a target initialization function source code corresponding to the initialization requirement of the target multiphase flow field through a main program of the numerical simulation software and a preset interactive interface of the dynamic link library, the method further includes: and determining a corresponding target initialization function source code according to the initialization requirement of the target multiphase flow field. Specifically, a target calculation domain, a target phase and a target area corresponding to a target in a target multiphase flow field are determined according to the initialization requirement of the target multiphase flow field; and determining a corresponding target initialization function source code according to the target calculation domain, the target phase and the target area corresponding to the target.
In one embodiment, a dam break algorithm, a typical multiphase flow problem, is initialized. Firstly, a developer writes an interface initflow (Q) for interaction between a main program and an external library, the interface provides a grid unit original variable array Q [7] and a unit coordinate array centroid [3] externally, the implementation mode is realized by using Fortran language, and a preset interface writing language does not limit a certain programming language. The preset interactive interface code is as follows:
ABSTRACT INTERFACE
SUBROUTINE initflow(Q, centroid) bind(c)
USE, INTRINSIC :: iso_c_binding
REAL(c_double),dimension(7),intent(inout) :: Q
REAL(c_double),dimension(3),intent(in) :: centroid
END SUBROUTINE
END INTERFACE；
further, the initialization requirement of the target multiphase flow field is determined, a schematic diagram of a calculating domain of a dam break calculation example is shown in fig. 3, the calculating domain is a rectangular region of [0, 1.61] mx [0, 0.9] m, water is in the range of [0, 0.6] mx [0, 0.3] m initially, and other regions are gas. The file name of the source code of the target initialization function is userDefineFunction.c, and the source code of the target initialization function is as follows:
#include<stdio.h>
#include<math.h>
void DamBreak(double Q[7], double centroid[3])
{
if(centroid[0]<0.6 && centroid[2]<0.3)
{
Q[5] = 0.0; //water
}
else
{
Q[5] = 1.0; //gas
}
}；
by the technical scheme, the initialization requirement of the target multiphase flow field is compiled into the corresponding target initialization function source code by using C language, so that the target initialization function source code is compiled into the corresponding target dynamic link library by the preset compiler in the following process.
Step S22: and compiling the target initialization function source code by using a preset compiler based on the operating system operated by the numerical simulation software to obtain a target dynamic link library corresponding to the target initialization function source code, and then adding path information and name information of the target dynamic link library in a configuration parameter file of a main program of the numerical simulation software.
In a specific embodiment, if the operating system in which the numerical simulation software operates is Linux, the GCC compiler is used to compile the source code of the target initialization function and obtain a target dynamic link library corresponding to the source code of the target initialization function. Specifically, compiling the target initialization function source code into a target dynamic link library based on the operating system environment and the compiler is as follows:
gcc -shared userDefineFunction.c -fPIC -o libuser.so -std=gnu99；
so, compiling the source code of the target initialization function and generating a target dynamic link library named as library. Further, a path of the dynamic link library and an initialization function name are specified in the configuration parameter file of the main program, and the following attributes are added in the parameter configuration file param.inf of the main program:
dynamicLibName = "../../libuser.so"
subroutineName = "DamBreak"；
and adding the path information and the name information of the target dynamic link library in a configuration parameter file of a main program of the numerical simulation software. Through the technical scheme, the corresponding target dynamic link library is generated, so that the target multiphase flow field can be initialized based on the target dynamic link library after the running instruction of the multiphase flow solving program is obtained subsequently.
Step S23: and acquiring an operation instruction of a multiphase flow solving program of the numerical simulation software, and initializing the target multiphase flow field based on the path information and the name information of the target dynamic link library in the configuration parameter file.
In this embodiment, a schematic diagram of an initialization flow of a multiphase flow field is shown in fig. 4, where the obtaining of an operation instruction of a multiphase flow solver of the numerical simulation software and the initializing of the target multiphase flow field based on the path information and the name information of the target dynamic link library in the configuration parameter file include: and acquiring an operation instruction of a multiphase flow solving program of the numerical simulation software, and calling the target dynamic link library based on the path information and the name information of the target dynamic link library in the configuration parameter file so as to initialize the target multiphase flow field.
In one embodiment, the initialization code is as follows:
mpiexec –n 16 ./mixture；
and calling the target dynamic link library based on the path information and the name information of the target dynamic link library in the configuration parameter file so as to initialize the target multiphase flow field and initialize the dam break calculation example, wherein a dam break initialization volume fraction cloud chart is shown in fig. 5. According to the technical scheme, the target initialization function source code is compiled into the target dynamic link library through the preset compiler, the explicit dynamic link library is adopted to enable the operating system function to realize the operations of loading, unloading and the like of the dynamic link library, the function address and the error information can be flexibly called, and compared with the static link library and the implicit dynamic link library, the method is more flexible, and therefore the method is more efficient in multi-phase flow field initialization.
Therefore, in the embodiment, the target multiphase flow field is initialized by calling the target dynamic link library, so that the method is more flexible compared with a static link library and an implicit dynamic link library and has higher operation efficiency compared with an interpretation method.
