Error when run make grid with customized ESGgrid

Dear community,

I tried to run a specifying custom ESGgrid based on the case (Link: https://dtcenter.org/sites/default/files/events/2021/13-defining-custom-domain.pdf). However, I met this error when I tried to make the grid (run_make_grid):

The settings for the grid in config.sh are exactly the same as the RRFS_SUBCONUS_3km in set_predefined_grid_params.sh. I am doing this because I want to have a test so that I can specify other domains (which also failed because of this error)

I am not sure which step(s) caused the nonpositive domain parameter. I have attached my config.sh and error file.

I've tested the model with a predefined domain, did not have this error.

 

Any helps are much appreciated,

When I set PREDEF_GRID_NAME="RRFS_SUBCONUS_3km" in config.sh and then run_make_grid, it worked.

I noticed the difference on arcx and arcy below:

I am not sure why arcx is the same but arcy in 0 when I set customized grid.
