MFEMHypreGMRES
Overview
Defines and builds an mfem::HypreGMRES solver to use as an iterative solver to solve the MFEM equation system.
Not compatible with use on partially assembled equation systems.
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
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:No
Description:Set the enabled status of the MooseObject.
