cfdforum4hyc New Member H. C. Join Date: Dec 2022 Posts: 5 Rep Power: 3	Hi, Thank you for reading! I'm a Blue-CFD user. Currently, I'm trying to run a multi process job using command "mpiexec" I input "mpiexec -np 12 simpleFoam -parallel" and received error information as below: $ mpiexec -np 12 simpleFoam -parallel ERROR: Failed to post close command error 1726 ERROR: unable to tear down the job tree. exiting... However, if I remove "-parallel", the simulation could run. Could anyone please help me by telling me how I should use mpiexec command in Blue-CFD correctly? BTW, I'm using Windows10 with MSMPI 10.1. Thank you in advance!
