MFEMTimeDependentWeakForm

Overview

The MFEMTimeDependentWeakForm is a MOOSE object responsible for the construction of an initialised MFEM TimeDependentEquationSystem, based on the set of kernels and boundary conditions provided by the user. If no MFEMWeakFormBase object is specified by the user in a real problem using an MFEMTransient executioner, a default MFEMTimeDependentWeakForm object will be created to set up a TimeDependentEquationSystem using all kernels and boundary conditions added in the input file.
