Hi,
I am having some issues with trying to use mpirun with simpleFoam that I would appreciate some help with. The setup of my problem is flow over a cylinder with a diameter of 1 meter (u_x = 1 m/s), and I am using the simpleFoam solver. My problem is that when I try to run the case in parallel using the command: Code:
mpirun -np (# of processors) simpleFoam -parallel > log & Code:
mpirun noticed that the job aborted, but has no info as to the process that caused that situation. Code:
foamJob -parallel simpleFoam > log & I am a relatively new user to OpenFOAM, so I am really curious why mpirun is not able to run my case in parallel, but foamJob can. I went through the damBreak tutorial and I had the same problem with mpirun that I am having with my cylinder flow case. I am really curious if anyone else has ran into this problem and used foamJob instead of mpirun to run a case in parallel. Thank you in advance for your time! |

hi,
this is my first time. i made weirOwerflow. i made blockmeshDict without errror. i am on the processes part. I wrote the "decomposePar" and created the processors and when I write "mpirun -np 4 interFoam -parallel >log&" Code:
--> FOAM FATAL IO ERROR: [2] cannot find file [2] [2] file: /home/ceren/weirOverflow/processor2/0/p_rgh at line 0. [2] [0] [0] [0] --> FOAM FATAL IO ERROR: [0] cannot find file [0] [0] file: /home/ceren/weirOverflow/processor0/0/p_rgh at line 0. [0] [0] From function regIOobject::readStream() [0] in file db/regIOobject/regIOobjectRead.C at line 72. [0] FOAM parallel run exiting what is the wrong? please help me. i am the beginner ![]() thanks Ceren. |
