FormSystem()

void Moose::MFEM::EquationSystem::FormSystem ( mfem::BlockVector &  trueX, mfem::BlockVector &  trueRHS  )

inherited

Build all weak-form components via BuildEquationSystem(), form the constrained linear part of the system, and populate the true-DoF vectors used by the solve.

For nonlinear problems, nonlinear forms are registered here but are not folded into the assembled linear operator. Their residual action is evaluated by Mult(), and any Jacobian contribution is formed at the current nonlinear iterate by GetGradient().

This is the single public entry point for callers that want the equation system prepared for a solve. Subclasses customize the form-building step by overriding BuildEquationSystem().
