type-id [Steady]:

NonlinearRomPreprocessing
Performs all offline preprocessing for ROM simulations, including those with hyper-reduction. Typically a single NonlinearRomPreprocessing simulation is used to construct all quantities needed for the online ROM simulation (with or without hyperreduction), though it can be split up as needed. See NonlinearRomPreprocessing.

SteadyNonlinearRom
Online steady-state nonlinear ROM computation. Is is recommended to set Time.Implicit.Type = SpatialOnly in this case.

UnsteadyNonlinearRom
Online unsteady nonlinear ROM computation.

AcceleratedUnsteadyNonlinearRom
Online accelerated unsteady nonlinear ROM computation. See Accelerated.

ForcedUnsteadyNonlinearRom
Online nonlinear ROM computation for forced oscillations of a rigid or flexible obstacle. See Forced.

SteadyNonlinearRomPostprocessing
Postprocessing to compute output quantities after an online steady-state nonlinear ROM computation.

UnsteadyNonlinearRomPostprocessing
Postprocessing to compute output quantities after an online unsteady nonlinear ROM computation.
