ROMHandler went through a major refactoring in order to support separate variable ROM.

  • ROMHandler is changed to an abstract class ROMHandlerBase. Only MFEMROMHandler class is available to use in practice.
  • If separate_variable, ROMHandler stores basis for each variable in each reference component as a separate basis tag.
  • MFEMROMHandler now have array dom_basis of pointers for each subdomain block basis.
  • ROMHandler supports various projection/lifting-up operation on Operator and Vector.
  • MultiBlockSolver supports ROM projection for separate variable basis.
  • StokesSolver run supremizer enrichment in order to keep inf-sup condition, if separate_variable_basis.
  • Anomaly is detected for StokesSolver and SteadyNSSolver FOM, when heterogeneous component meshes are used. Bug fix includes:
    • Now ComponentTopologyHandler enforces all the component meshes to have the same FiniteElementCollection.
    • SteadyNSSolver enforces all the component meshes to have the same element type.
