AddVariableMappingAction

This action adds VariableMappingBase objects contained within the [VariableMappings] block. For example, the following block adds a PODMapping mapping object.

[VariableMappings<<<{"href": "../../syntax/VariableMappings/index.html"}>>>]
  [pod_mapping]
    type = PODMapping<<<{"description": "Class which provides a Proper Orthogonal Decomposition-based mapping between full-order and reduced-order spaces.", "href": "../variablemappings/PODMapping.html"}>>>
    solution_storage<<<{"description": "The name of the storage reporter where the snapshots are located."}>>> = parallel_storage
    variables<<<{"description": "The names of the variables which need a mapping."}>>> = "v"
    num_modes_to_compute<<<{"description": "The number of modes that this object should compute. Modes with 0 eigenvalues are filtered out, so the real number of modes might be lower than this. This is also used for setting the subspace sizes for distributed singular value solves. By default, the subspace used for the SVD is twice as big as the number of requested vectors. For more information see the SLEPc manual. If not specified, only one mode is computed per variable."}>>> = '2'
    extra_slepc_options<<<{"description": "Additional options for the singular/eigenvalue solvers in SLEPc."}>>> = "-svd_monitor_all"
