Hi eveyone
I'm using p_top=50 hPa and e_vert=34 to run WRF-Chem, but it take so long time for my simulation , so I want to apply p_top=500 hPa and e_vert= 20 ,even p_top=700 hPa with e_vert=15. But both of them failed in wrf.exe(even though succeed in real.exe). I take some test and find it should be my vertical layers settings causing the failure. Before I dig into e_vert, ptop, dzbot, dzstretch* deeper, I wonder if it's reasonable to apply e_vert < 20 for WRF.
PS: This is the error message:
