Error running mesh option

[TimNmn]

Dear Jonathan,

I've found your plugin and would like to use it in order to create meshes for the use in Telemac. I've installed it the way you described. I'm using qgis for mac in version 3.28.13-Firenze as ltr.

Creating .geo files works just fine, but trying to mesh gives errors, which I don't know how to handle.

Do you have any recommendations what to do and how to fix this?

Best regards Tim

Hi Sebastien, Thank you for your reply, I’ve had a look to the image you send. The opportunity to choose the path did not show up for me. I used the newer qgis plugin QGIS-GMSH as this has the version number 0.2.4. In respect to your mail I had a go on the version 0.2.2 which is still available in the plugin repository. There I found the window regarding the path selection. However, following the tutorial the plugin seems not to work at the moment running it on Mac. I did manage to generate a mesh running the procedure on a windows remote machine. I guess this will be the best way for me at the moment. If you still have any further advice it'll be much appreciated. Best Tim

In recent qgis-gmsh plugin, gmsh is called through its python api, not through the executable. Normally the installation of the python gmsh module is automatic. In your case it seems that the problem comes from the lines :
args = [sys.executable, "-c","import gmsh; import sys; argv=['gmsh']+sys.argv[1:];gmsh.initialize(argv,run=True); gmsh.finalize();", "-2", self.inputGeo.getFile(), "-algo", algo, "-format",fmt, "-epslc1d", self.epslc1d.text(), "-o", self.outputMsh.getFile()] + shlex.split(self.commandLine.text()) self.runGmshDialog.exec_(args)
where sys.exectuable is supposed to be the python executable used by qgis which does not seems to be the case on your computer.
