I tried to debug it but couldn't find any solution yet. Can someone help to understand what is this error about?

Thank you!

Hi jaslanli,

Have you been able to find a way to solve this problem? I have the same issue. I tried redownloading the input wind and reprocessing it in the prnc, but that wasn't the solution. Maybe something with the time steps ?

Glad if you answer me.

Thank you!

Two things to try:

1. Increase your memory that you allocate to your job incase you are just simply running out of memory.
2. Print out values from model/src/w3src4md.F90:952 to see if bad values are causing the issues.
