What is 'GeoMesh' wrapper?

granzer · November 3, 2020, 07:08

Hello, can someone please explain what the GeoMesh wrapper class does? I know it is used to wrap volMesh, surfaceMesh, pointMesh, but what does wrapping these meshes with GeoMesh achieve?

Also, volMesh, surfaceMesh, pointMesh themselves seem to be derived by wrapping the fvMesh class with GeoMesh. Why is this done?

Any info on this please?

I think:

For a given utility (e.g. decomposePar), GeoMesh template gives access to all types of meshes. Therefore, say decomposePar, can be executed for all mesh types that GeoMesh wraps. Benefit: easier maintainability, lesser code, better structure etc.

@HPE thank you for your answer. Yes I have seen it used in few places. Especially in GeometricField(Field, PatchField, GeoMesh) class. Here the GeoMesh can be volMesh or surfaceMesh etc. Let's say it's volMesh. The volMesh class inherits from GeoMesh<fvMesh> class. Why not inherit directly from fvMesh. Why use GeoMesh<fvMesh> (correct me if I am wrong...here 'fvMesh' is wrapped by 'GeoMesh' class right?)
