Motivation

Patterning mesh generators such as FlexiblePatternGenerator and PatternedHexMeshGenerator sometimes need input meshes that are generated by the same mesh generator with variation in some input parameters. Currently, this would need many similar input blocks, making the input file unnecessarily big. It would be helpful to consolidate these similar blocks into one.

Design

Adding a batch mesh generation action to enable generating multiple meshes using one single input block.

Impact

Better user experience.
