rom: Galerkin: hyperreduced problem

API, Parameters and Requirements

problem = galerkin.HyperreducedExplicitProblem(scheme, fom_adapter, decoder, \      (1)
                                               rom_state, fom_ref_state, projector)

problem = galerkin.HyperreducedImplicitProblem(scheme, fom_adapter, decoder, \      (2)
                                               rom_state, fom_ref_state, projector)

• scheme:
  • value from the ode.stepscheme enum setting the desired stepping scheme
  • (1) requires explicit value
  • (2) requires implicit value
• fom_adapter:
  • instance of your adapter class specifying the FOM problem.
    
  • must satisfy one of the APIs suitable for Galerkin, see API list
• decoder:
  • decoder object
  • must satify the requirements listed here
• rom_state:
  • currently, must be a rank-1 numpy.array
• fom_ref_state:
  • your FOM reference state that is used when reconstructing the FOM state
  • must be a rank-1 numpy.array
• projector:
  • performs the projection of the FOM operators onto the reduced space
  • must meet this specific API
