No file in mesh directory

Hi Jean, I was able to get the singularity image working and I can properly import everything however I believe that there was some type of problem with how I have gmsh setup.

These are the files in the current directory:

ls
fenics-and-more.img  
Cylinder2DFlowControlDRL-master    gmsh-3.0.6-Linux64

And this is the command I ran to setup singularity and gmsh:

singularity shell fenics-and-more.img -c "export DISPLAY=:0.0 && export PATH="gmsh-3.0.6-Linux64/bin:$PATH" && /bin/bash"

Then I ran single_runner.py in the empty_simulation folder to get this error output.

It can’t find some file that is supposed to be in the mesh folder, my best guess is that gmsh isn’t generating the file that it is looking for. But I don’t know what I could have done incorrectly with gmsh. Thanks for the help

Thank you I did setup gmsh incorrectly and after adding to the path variable correctly I now can run the provided training sessions. The mistake I made was when I set my path variable it did not go from the root directory to the gmsh folder and instead went from the directory I started the singularity shell .

export PATH=$PATH:"path from root to gmsh bin folder"
