> I see. It looks like Itasca 5 was last updated in mid-2019. I assume they have their reasons for both embedding FiPy and not updating it in a recently-supported version. If they're running a Python interpreter, it should be possible for you to manually update FiPy, but you'd need to ask the Itasca developers how to do that. #903

I tried Mr. Furtney solution way, that pass this error and I'm now facing with new error which, I think, is related to my windows variables ... .

OK, what is the new error?

Dear Dr.Guyer: Now I am also troubled by the same problem. I wonder if you can help me find a solution. Gmsh3D.zip

When I input the code(with Mr. Furtney solution way) in the attachment in PFC6.0 (the software has built-in version 3.6.1 of Ipython), the following error message appears:

IndexError Traceback (most recent call last) C:\Program Files\Itasca\PFC600\exe64\python36\lib\site-packages\fipy\meshes\gmshMesh.py in read(self) 793 ghostsData, --> 794 facesData) = self._parseElementFile() 795

IndexError: list index out of range

During handling of the above exception, another exception occurred:

Itasca is not our software and, as you quoted, they apparently embed a four year old version of FiPy. Current FiPy does not raise an error on this mesh.

Please contact Itasca for support.

Thank you very much, Dr.Guyer. Best wishes!
