CGNS file name etc.

Abstract

“CGNS file name” and “Calculation result in CGNS file” is used together.

Widget to select CGNS file name can be created with valueType attribute “cgns_filename”.

Widget to select calculation result in CGNS file can be created with valueType attribute “result_gridNodeReal” etc., and cgnsFile attribute that refers the name of “CGNS file name” widget.

An example of definition to display widget to select CGNS file, and widget to select calculation result with real values defined at grid nodes, that is contained in the CGNS file, are shown in List 53. The widgets created with the definition are shown in Figure 58.

An example of FORTRAN programs to read the values that users have input with the widgets are shown in List 54 and List 55.

List 54 Code example to load CGNS file name and Calculation result in CGNS (for calculation conditions and grid generating conditions)

integer:: ier
character(200):: cgnsName, resultName

call cg_iric_read_string(fid, "input_file", cgnsName, ier)
call cg_iric_read_string(fid, "result_to_read", resultName, ier)

List 55 Code example to load CGNS file name and Calculation result in CGNS (for boundary condition)

integer:: ier
character(200):: cgnsName, resultName

call cg_iric_read_bc_string(fid, "inflow", 1, "input_file", cgnsName, ier)
call cg_iric_read_bc_string(fid, "inflow", 1, "result_to_read", resultName, ier)

Calculation result types and corresponding “valueType” values

The list of calculation result types and corresponding “valueType” values are shown in Table 9.
