About block naming

[Blackfoxdragon]

I assembled the mesh generated by the PolygonConcentricCircleMeshGenerator module using the PatternedHexMeshGenerator module; however, for each identical mesh from the PolygonConcentricCircleMeshGenerator, their inner rings share the same block ID. Now, I want to create a unique ID for each inner ring without repeatedly using the PolygonConcentricCircleMeshGenerator module. Is there any way to do this?

@miaoyinb thoughts?

I would say we can do this now with:

• ExtraIDAux to use the assembly_id / various reporting ids to set an auxvariable
• ParsedAux to create a new_block_id variable from the assembly_id that will be used by the VariableValueElementSubdomainModifier

I can work on it if this plan works for you.

Works for me.

Lets do ParsedSubdomainIDsGenerator though. Better name

Sounds good, I will open an issue tonight.

I'm thinking if you inherit from the ParsedSubdomainGznerator/use a shared base class you won't have too much that's different?

[miaoyinb]

I will try that.
