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
