When my grid resolution is reduced to 300m and time step is reduced to 20/27s, after running WRF calculations with the above parameters for about 10s, I get an error and segment fault, invalid memory reference, I have set ulimit -s unlimited before running, and it stack size unlimited.
The above 300m model is based on ndown .exe of 900m grid’s result and the terrain is flat, located on the beach and the computer is running on 64 cores.
Anyone who can provide me with help would be greatly appreciated.
