Hello,
I have just upgraded to macOS Big Sur and am using python 3.8.2 and NGSolve 6.2.2102. I am trying to run netgen in batchmode from a python script. I am using the command
subprocess.call(['netgen','-geofile=my_geometry.geo','-meshfile=my_mesh.vol','-coarse','-batchmode'])
Which I believe to be equivalent to
$ netgen -geofile=my_geometry.geo -meshfile=my_mesh.vol -coarse -batchmode
However, the second works but the first does not and I receive the following error
Error in Tcl-Script:
result = dlopen(libgui.dylib, 6): image not found
Make sure to set environment variable NETGENDIR to directory containing ng.tcl
I have been running the first line of code on macOS High Sierra and I believe the only thing I have changed is my OS. Could you please advise if there is something I have missed or if there is an easy work around?
Kind regards,
Ben
