gsmh about calfem-python

[jonaslindemann]

Make sure to install GMSH (http://gmsh.info/) and add it to the search PATH in Windows. In anaconda GMSH can be installed by using

conda install python-gmsh

gmsh is in the PATH (i can launch it by "gmsh" in cmd), but issue is still occured

Traceback (most recent call last):
File "form_plate_mesh.py", line 26, in
coords, edof, dofs, bdofs, elementmarkers = mesh.create()
File "D:\Programs\Python3-64bit\lib\site-packages\calfem\mesh.py", line 256, in create
"Error: Could not find GMSH. Please make sure that the \GMSH executable is available on the search path (PATH).")
OSError: Error: Could not find GMSH. Please make sure that the \GMSH executable is available on the search path (PATH).

Hello... did you find a solution for this issue? I'm having the same problem and I'm not being able to fix it by adding to the PATH

[MaximilianFranz]

Probably a more stable variant to find the path of the gmsh executable during runtime is something like:

>>> import subprocess
>>> import os
>>> cmd = "which"
>>> subprocess.call([cmd, "gmsh"])
/opt/conda/envs/modugen-core/bin/gmsh
0
>>>

It's important to distinguish between Windows and Linux systems.

I have updated the detection mechanism to be able to find gmsh in more places. Site-packages are also searched now.
