Hi all,
I put a job on a remote server to run WRF-Chem. However, after checking rsl.error.0000 I faced this message:

We recommend contacting wrfchemhelp for assistance.

After 9 hours it stays at this step (no aerosols initialization yet ). Is it something normal? If not, how can I sort the issue out, please?
I appreciate any help.
Best regards,
Hi Adriana, I am also having this same issue. I had a version of WRF Chem 3.8.1 that would run well but when I am trying to run the same namelist.input, it gives me this error. There seems to be some problem related to AQ chemistry in the newer v4 versions. Please let me know if you find the solution.
