Meshing issue with tests

[Angus]

Dear SLIM forum members,

I am interested in using SLIM. I cloned it from GitLab yesterday, and managed to successfully compile it.

However, when I try to run any of the tests, they almost always fail. For instance, running shallowWater/tests/stommel,

> slim ./test.py

gives me:

Warning : Surface 6 consists of no elements
Info : Meshing surface 7 (Plane, Delaunay)

I get similar meshing errors for every test I’ve tried, shallow water or 3D. I am using GMSH 3.0.6.

Would anyone have an idea what might be wrong?

Regards

You may have a global gmsh options file with options incompatibles with the .geo files of the examples.
Can you try to :
– open gmsh
– activate the menu item « Help->Restore All Options To Default Settings »
– activate the menu item « File->Save Options As Default »
– close gmsh
– try the example again.

Cheers,
Jonathan
