MFEMProblem
Overview
MFEMProblem is derived from MOOSE's ExternalProblem Problem type, customized to set up the finite element problem using the MFEM FE library instead of MOOSE's default libMesh. Use of MFEM allows problem assembly and solution on GPU architectures as well as on CPU; desired device can be controlled by the MFEMProblemSolve object used to solve the problem.
MFEMProblem methods are called by Actions during parsing of the user's input file, which add and/or initialize members of the owned MFEMProblemData struct. The order in which these actions are executed respects the dependencies declared in Moose.C.
Example Input File Syntax
In order to build the FE problem using the MFEM library on the backend, the MFEMProblem type must be used in Problem block in the user input.
