[snappyHexMesh] setFields does not work after running snappyHexMesh parallely

vava10 · March 1, 2021, 16:10

Hey everyone,

my work flow is as follows

Code:

1. surfaceFeatureExtract
2. blockMesh
3. topoSet1
4. refineMesh
5. topoSet2
6. refineMesh
7. topoSet3
8.  refineMesh
9. decomposePar
10. mpirun -np 4 snappyHexMesh -parallel
11. reconstructParMesh
12. setFields

this workflow did not give me any error in the terminal

after this when I try to view the setField results I was unable to visualize the result. I have been trying to resolve this for a week. recently I tried to run the snappyHexMesh without using parallel (just using 1 processor). Then I tried to visualize the result and I was able to visulaize it.

I tried parallel running using the info got from this link : https://www.openfoam.com/releases/op...+/parallel.php

it also did not help

openFoam version - v2012

from all this I came to conclusion there is something wrong with the parallel running portion of the work flow.
So I tried few of the suggestion from different error posted in the form regarding parallel run. But still I was unable to fix it

CAn some one PLEASE help me

if you need further information regarding the case set up please feel free to ask

Kind regards

>decomposePar
>mpirun -np 4 snappyHexMesh -parallel -overwrite
>reconstructParMesh –constant

this worked for now for this issue
