cg_iRIC_Read_Grid_TriangleElements_WithGridId

Reads IDs of nodes constituting the triangles of the unstructured grid.

You should pass an array with size (numcells * 3) for id_arr. The returned values of ids will be the IDs of nodes for each triangles. 1st, 2nd, 3rd values will be the IDs of nodes of the 1st triangle, 4th, 5th, 6th values will be the IDs of nodes of the 2nd triangle, etc.

Format (FORTRAN)

call cg_iRIC_Read_Grid_TriangleElements_WithGridId(fid, gid, id_arr, ier)

Format (C/C++)

ier = cg_iRIC_Read_Grid_TriangleElements_WithGridId(fid, gid, id_arr)

Format (Python)
