It is recommended to perform these steps once in GMSH manually and to transfer the CutPlane parameters to the script above. This script loads the density and the velocity plot of a given time step and performs the CutPlane plugin four times in order to restrict the resulting vector plot to the region around the target surface.

#Gmsh parallel how to
I am not sure how to implement that though, will be grateful for any advice or clarification on the issue.Within the. Can gmsh be used in parallel? If not, how to do it instead? I am thinking of running the script in series, and within the script run only the actual solving in parallel.
So I think it might be connected to gmsh. I have obtained similar “segmentation fault” errors previously (when still running in series) only when there was trouble with gmsh. In the script, I run gmsh from the terminal via subprocess and then meshio. I have tried running the demos in parallel and it works, so I expect the problem to lie within my script. I tried to run my script in parallel, but obtained the following error:
