Thanks Duyen for opening this as a separate thread.
Have you had a chance to consider the suggestion posted by @cjcoats and myself in the original thread (here and here) to double check that the grid name specified through the GRID_NAME variable in your icon run script (SE52BENCH) is actually present in your GRIDDESC file (/home/Build_WRF/WRFV3/run/metdata_Phong/demo1/GRIDDESC)? In your icon run script, you need to set GRID_NAME to one of the grids defined in your GRIDDESC file.
