Impose 1 cell meshing over a geometry
 

Hi all,

I am doing a solid hydrogen storage comsol model and I want to impose a meshing restriction over one geometry. I want to have just one cell in this part of the geometry. How can I do this?

The domain where I want to implement one cell grid instead of a more complex mesh is the red-dotted one in the attached figure.

Thank you.
Regards.

Jose.
