NaN when restart parallel
 

Hi! I have a simple airflow model created in pro-am v3.26 and BCs setup in v4.08. total cells only 1.2 Million. On windows I can only run in single cpu. Trying to run in parallel, I got all kinds of mpich, smpd and mpiexec errors and I have re-installed v4.08 twice today. Then I switched to Linux. On linux it could run in parallel but everytime I restart the model (changing URF), it gave NaN errors. :confused:
Any help or idea will be useful!
thanks!
