@Rainzmh – I’m sorry you are getting this error. Can you also give me the last bit of your log file, too, please? If you can also get a more specific line from the traceback (that is, which line in setup_wrfem.f90 is causing the problem), then I can help you more quickly. You may be able to get …

I think there may be something wrong in my wrfout file.But unfortunately I don’t konw how to check my fault.Should I use the benchmark dataset first?Could you please provide the website link to me?Thanks a lot!
