about geometry dimension, working space dimesion and local space dimension

[miguelmaso]

Description
Recently I had some confusions using the geometry dimensions. As an example, some of the geometries define the following dimensions:

	Dimension	Working space dimension	Local space dimension
Line3D2	3	3	1
Triangle3D3	2	3	2
Tetrahedra3D4	3	3	3
Line2D2	2	2	1
Triangle2D3	2	2	2
Quadrilateral2D4	2	2	2

On the one hand side, there are three dimensions defined. From my point of view, there are only two spaces: the local space and the global/working one. What does mean dimension? On the other hand, how is it possible that the Line3D2 has dimension=3 and the triangle3D3 has dimension=2?

This confuses me as well

I've the feeling that Dimension is legacy and what one should trust is WorkingSpaceDimension and LocalSpaceDimension (what is what we normally do).

@KratosMultiphysics/technical-committee We are discussing how to make Dimension() consistent. Since this is hardly doable automatically (can't do search and replace), our suggestion is to deprecate Dimension() and use WorkingDimension() or LocalDimension()

The way to go should be:

• Deprecateor remove Dimension()
• Manually change calls to Dimension() (should be ~100)
• Finally delete Dimension()

I think that after #10977 the roadmap is completed 🎉
