PDE-Models

Classes which define some diffusion dominated PDE models. More...

Modules
	ModelParameters
	Parameters are quasi-constant quantities, like the time-step size in one time-step when solving transient problems with finite element methods.
	Model Building Blocks
	Basic PDE-Models which can be used to conveniently form more complicated models by means of ModelExpressions.
	ModelInterface
	Interface definition for a model for a non-linear diffusion dominated model in the context of continuous FEM.
	BoundaryIndicators
	see BoundaryIndicatorInterface
	DynamicPolymorphism
	In the style of the dune-fem-school-generator we define here dynamic problem descriptions and an EllipticModel such that an application can switch between example problems at run-time.
	ModelTests

Detailed Description

Classes which define some diffusion dominated PDE models.

A model in this sense provides "germs" for the integrals which finally form the weak formulation. That is, the methods a model defines form one factor of the bilinear forms, the multiplication by test-functions and their jacobians is then handled by Fem (see EllipticOperator).
