I am using WRF version 4.5 for my simulation. After customizing eta_levels, I cannot run ./real.exe properly. The error message and namelist.input are as follows. I have checked many blogs but still haven’t solved the issue. I also referred to the instructions in the best practice guide and changed parent_id to start from 1, but it still doesn’t work. Could anyone help me take a look? Thank you very much!!
