Enumeration Type Documentation

◆ DiffMethod

enum class Dumux::DiffMethod
strong

Differentiation methods in order to compute the derivatives of the residual i.e. the entries in the jacobian matrix.

Todo:
automatic differentation is not yet implemented
Enumerator
numeric 
analytic 
automatic 

◆ EntityColor

enum class Dumux::EntityColor
strong

The colors of elements and vertices required for partial Jacobian reassembly.

Enumerator
red 

distance from last linearization is above the tolerance

yellow 

neighboring entity is red

orange 

A yellow entity that has only non-green neighbor elements.

This means that its relative error is below the tolerance, but its defect can be linearized without any additional cost.

green 

does not need to be reassembled

template<class FEBasis >
Dune::MatrixIndexSet Dumux::getFEJacobianPattern ( const FEBasis &  feBasis)

Note
This interface is for compatibility with the other schemes. The pattern in fem is the same independent of the time discretization scheme.
