I use pxlsm and can successfully run the ACM2 scheme with three levels of nesting (36.12.04km).
But when I run 12km and 04km separately, I got this error. 36km can run successfully.
Model crashed immediately
I modified the timestep, but it didn't work. I changed the land type (mentioned in other posts in the forum), but it didn't work. I only use wrfbdy and wrfinput as input files, I use WRF4.3 and WPS4.4. The 04km simulation domain is located in the river plain, and there should be no very steep terrain.All other scheme can run successfully， but I really need PX lsm. I am using FNL data.
How can I fix this problem? Looking forward to your help! ! !
