1st, selection section is in interface is set, and user can select to create the section of coupling in the drop-down list of section.Choosing
Select behind section,
According to upstream and downstream order in the left list of interface, all sections are listed line by line in units of adjacent sections.
2nd, selection section group, which is clicked on, chooses certain row, and system chooses corresponding section in map interface automatically；The row is double-clicked,
Can quickly position to
Corresponding region.If the section group has set the side member of association, corresponding sides member is highlighted simultaneously.Section group can
Single choice also can multiselect.When multirow in choosing, all sections chosen and side member list are highlighted by system.It is as shown below：
3rd, set during the laterally attached setting of member of left and right bank, it is necessary to distinguish left bank or right bank of the side member positioned at section.Judge
Mode is that left side is left bank, and right side is right bank according to the direction that downstream is swum over to from river course.When single section group in choosing, this
The side member for locating selection sets up vertical coupled relation with corresponding section automatically.When multiple section groups in choosing, system according to section with
The position relationship of side member, will choose side member to be assigned to cross sections group automatically.Automatically the result calculated may not conform to the actual conditions, especially
It is river course complex-shaped, that bending is larger, and the probability of result of calculation error is larger.Therefore, needed after batch setting to coupling
Information is checked and changed.
4th, the editor of coupled relation
5th, left and right banks is exchanged：When setting laterally attached, there is left and right banks and reverse possibility is set.To avoid user from repeating
There is provided the function that left and right banks is exchanged for operation.
6th, during automatic distinguishing left and right banks selection side member, user directly can choose left and right bank member simultaneously using frame selection tool.
Now, all side member lists are deposited in same row.
7th, remove link information and choose single or multiple section groups, the corresponding side metamessage of selected section can be removed.
Positive linkage record river course head and the tail section and a series of coupling information of sides member.Its basic operation and laterally attached class
Seemingly, explanation is not repeated herein.
After the structure for completing urban pipe network and two-dimensional shallow water model, newly-built two-dimentional pipe network coupling figure layer is created while ejecting
Two-dimentional pipe network coupling elements interface, is named and selects pipe network key element and two-dimensional grid, and topological relation is created and finished.
Newly-built pipe network coupling elements appear in left side layer management region, can carry out setting up it is laterally attached, delete key element,
The setting of layer properties.Set up lateral when being connected to calculating earth's surface and confluxing, in order to consider the open pipe of city river or part
Canal interacts water (such as river course overflows), it is necessary to set up the laterally attached of pipe duct and two-dimensional grid by two sides and earth's surface.Selection
Need the pipeline section and element sides of connection and tolerance is set, complete laterally attached foundation.Can it is existing it is laterally attached on carry out
Inquire about pipeline section and element sides, the operation of adding device side of connection.
