Detailed Description

Abstract non-adaptive basic FEM scheme.

Used as solver black-box, so to say.

Member Function Documentation

solve()

virtual void Dune::ACFem::BasicFemScheme::solve ( bool  forceMatrixAssembling = true )

pure virtual

Solve the system.

Parameters

[in]

forceMatrixAssembling

If the solve step requires assembling of matrices, then by default the application may give a hint to the FemScheme that this might not be necessary. The actual implementation can then decide if it caches the assembled matrix from the last solve() invocation and reuses it. If forceAssemble is true then the implementation has to discard and cached assembled matrices and recompute them.

Implemented in Dune::ACFem::ParabolicFemScheme< DiscreteFunction, TimeProvider, ImplicitModel, ExplicitModel, InitialValue, RHSFunctional, QuadratureTraits >, and Dune::ACFem::EllipticFemScheme< DiscreteFunction, Model, InitialGuess, RHSFunctional >.
