I am testing WRFV4.1 with sf_ocean_physics=2 and enabling preset moving nest. The program crashes without any errors in rsl.error files. When I disable 3d-ocean and set sf_ocean_physics=0, the model runs fine, indicating that the issue may be related to 3dPWP. Additionally, when I deactivate the 3d-ocean options, the model runs at a quite slower speed than fixed nesting run, leading me to question if my namelist is correct. I would appreciate it if someone helps me.
