Detailed Description

Some models for the "right hand side", L2 "bulk forces" and DiscreteLinearFunctionals.

The two basic models defined here are

• BulkForcesFunctionModel in order to add an L2-function to the right hand side.
• ForcesFunctionalModel in order to add a globally defined functional.

The most simple way to add these models is to use ModelExpression templates, see

• operator-(const ModelInterface<Model>&, const Fem::Function<typename Model::FunctionSpaceType, GridFunction>&)
• operator-(const ModelInterface<Model>&, const DiscreteLinearFunctional<DiscreteFunctionSpace, Traits>&).

like follows, given an existing model and grid-function F:

MyGridFunctionObject F;
auto newModel = existingModel - F;
