virtual void correct()
Correct the motion diffusivity.
An Istream is an abstract base class for all input systems (streams, files, token lists etc)...
Definition: Istream.H:57
Macros for easy insertion into run-time selection tables.
dimensionedScalar exp(const dimensionedScalar &ds)
bool readScalar(const char *buf, doubleScalar &s)
Read whole of buf as a scalar. Return true if successful.
Definition: doubleScalar.H:75
exponentialDiffusivity(const fvMesh &mesh, Istream &mdData)
Construct for the given fvMesh and data Istream.
addToRunTimeSelectionTable(ensightPart, ensightPartCells, istream)
Abstract base class for cell-centre mesh motion diffusivity.
defineTypeNameAndDebug(combustionModel, 0)
Mesh data needed to do the Finite Volume discretisation.
Definition: fvMesh.H:95
virtual ~exponentialDiffusivity()
Destructor.
virtual tmp< surfaceScalarField > operator()() const
Return diffusivity field.
A class for managing temporary objects.
Definition: PtrList.H:53
static autoPtr< motionDiffusivity > New(const fvMesh &mesh, Istream &mdData)
Select null constructed.
