Hi<br><br>I have been trying to run WRF with 5 domains. Even though the real.exe runs successfully, the following errors come for the inner most domain the the mpi run exited. The errors are like as follows:<br>--------------------------------------------------------------------------------------------------------------------------------------------<br>
