8 months ago I am using Pycharm SSH connected to a Linux server that has Python 3.11.2 From the package window of Pycharm, I can see that it has Fipy 3.4.4 and Gmsh 4.11.1 installed and both are in the same directory.
However, I have this error 'OSError: Gmsh version must be >= 2.0.'
What is the result of
import fipy as fp
print(fp.gmshVersion())Cannot use
import fipy fipy.test()to check the setting of the solver since the server does not allow me to do so.
Please explain.
This one suggests that Gmsh should be installed before installing Fipy or I will get the Gmsh version error. However, I tried installing Fipy and then reinstalling Fipy, still got the Gmsh version error. I also tried installing Fipy and Gmsh and then installing Gmsh first followed by installing Fipy. Still the same error.
The order of installation doesn't matter.
I'm relying on a google translate of that page, but I don't see anywhere a discussion of what order to install FiPy and Gmsh. As far as I can tell, the issues are because they're attempting to read an msh4 file, which FiPy doesn't support. It looks like they tried to convert it to msh2, using both gmsh and meshio, but apparently that didn't work, either. Hard to tell; they never bothered to ask us for help.
This one suggests that 'application (.exe) has to be in the directory with python modules' but I am trying on Linux server so there is no .exe file, plus I do not have the authority to modify the system-level directory. So I haven't tried this method yet.
That's all about Windows and doesn't apply on Linux. Gmsh needs to be on your $PATH. Let's work on figuring out if it is.

I am using Pycharm SSH connected to a Linux server that has Python 3.11.2 From the package window of Pycharm, I can see that it has Fipy 3.4.4 and Gmsh 4.11.1 installed and both are in the same directory.
However, I have this error 'OSError: Gmsh version must be >= 2.0.'
The line in my code
mesh = Gmsh3D("cube.geo")in my code that caused the error. This line of code calls other functions under the file 'fipy/meshes/gmshMesh.py'. So I think the fipy on the server was trying to call the wrong Gmsh tool. But I am not sure how to check who this fipy is trying to call.Before getting this Gmsh version error, I got an error says that Gmsh was not defined so I just installed Gmsh into the server (I assume that there is an import gmsh command somewhere in fipy and that might trigger the gmsh not defined error if gmsh is not installed). And after installing Gmsh, I saw the Gmsh version error.
For the server safety issue, the Python interpreter and site packages are not in the same level. The Python is installed in the system-wide level /bin directory which site packages are installed in the user environment. But I assumed that the PATH to the user environment is pre-setted and this is why Pycharm could find the packages in the user directory. And since I confirmed that the Fipy and Gmsh are in the same site package directory, I cannot understand why Fipy cannot find the correct Gmsh.
Cannot use
import fipy fipy.test()to check the setting of the solver since the server does not allow me to do so.The code is running fine if using my local interpreter (either on Win11 or WSL on Win11).
