MFEMHypreADS
Summary
Hypre auxiliary-space divergence solver and preconditioner for the iterative solution of MFEM equation systems.
Overview
Defines and builds an mfem::HypreADS solver to use as a preconditioner or solver to solve the MFEM equation system. Most effective for preconditioning and solving a grad-divergence problem when using Raviart-Thomas elements, in which case the FE space should be passed to the mfem::HypreADS solver during construction.
A Low-Order-Refined (LOR) version of this solver may be used instead by setting the parameter "low_order_refined" to true. Using an LOR solver improves performance for high polynomial order systems.

[]Input Parameters
- allow_duplicate_execution_on_initialFalseIn the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).
Default:False
C++ Type:bool
Controllable:No
Description:In the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).
- execute_onTIMESTEP_ENDThe list of flag(s) indicating when this object should be executed. For a description of each flag, see https://mooseframework.inl.gov/source/interfaces/SetupInterface.html.
Default:TIMESTEP_END
C++ Type:ExecFlagEnum
Controllable:No
Description:The list of flag(s) indicating when this object should be executed. For a description of each flag, see https://mooseframework.inl.gov/source/interfaces/SetupInterface.html.
- execution_order_group0Execution order groups are executed in increasing order (e.g., the lowest number is executed first). Note that negative group numbers may be used to execute groups before the default (0) group. Please refer to the user object documentation for ordering of user object execution within a group.
Default:0
C++ Type:int
Controllable:No
Description:Execution order groups are executed in increasing order (e.g., the lowest number is executed first). Note that negative group numbers may be used to execute groups before the default (0) group. Please refer to the user object documentation for ordering of user object execution within a group.
