Value defined at grid cells

When you output value defined at grid cells, please use the functions in Table 74.

List 104 shows an example of the process to output value defined at grid cells.

Table 74 Subroutines to use for outputting result defined at grid cells

Subroutine

Remarks

cg_iric_write_sol_cell_integer

Outputs integer-type calculation results, having a value for each grid cell

cg_iric_write_sol_real

Outputs double-precision real-type calculation results, having a value for each grid cell
