template<typename CeedOperatorInfo , typename CoeffType >
void Assemble (CeedOperatorInfo &info, const mfem::FiniteElementSpace &fes, const mfem::IntegrationRule &ir, CoeffType *Q)
 This method assembles the MFIntegrator with the given CeedOperatorInfo info, an mfem::FiniteElementSpace fes, an mfem::IntegrationRule ir, and mfem::Coefficient or mfem::VectorCoefficient Q. The CeedOperatorInfo type is expected to inherit from OperatorInfo, and contain a Context type relevant to the qFunctions. More...
