cg_iRIC_Read_Grid2d_Interpolate

Returns the information to interpolate the value at the specified coordinates, with the values defined at grid nodes.

The value of g_handle that should be passed to this function, can be obtained by calling cg_iRIC_Read_Grid2d_Open or cg_iRIC_Read_Sol_Grid2d_Open.

Format (FORTRAN)

call cg_iRIC_Read_Grid2d_Interpolate(grid_handle, x, y, ok, count, nodeids_arr, weights_arr, ier)

Format (C/C++)

ier = cg_iRIC_Read_Grid2d_Interpolate(grid_handle, x, y, ok, count, nodeids_arr, weights_arr)

Format (Python)

ok, count, nodeids_arr, weights_arr = cg_iRIC_Read_Grid2d_Interpolate(grid_handle, x, y)
