Hello Emanuele. I mesh the .geo file in gmsh myself, and use both "optimize 3D" and "Optimize 3D (Netgen) sequentially before saving my mesh. That way I almost never have any mesh volumes below 0.3 quality. Is this the case for you? When starting a SPIS project, I therefore always skip the geometry editor when creating a new SPIS project.

If you're still having problems I suggest simplifying the thruster model.

Hello, I am trying to create a simple domain to simulate the plume of a Hall Thruster. However, I cannot create a mesh with an acceptable minimum cell quality. The domain is quite simple: the thruster and a semisphere as the external boundary, do you know if there are some best practices that I can use to get a good mesh quality? Thanks,
