Description

template<class TypeTag>
class Dumux::FvMpfaO2dVelocity2P< TypeTag >

Class for calculating velocities from cell-wise constant pressure values.

Calculates phase velocities or total velocity from a known pressure field applying a finite volume discretization and a MPFA O-method. At Dirichlet boundaries a two-point flux approximation is used. The pressure has to be given as piecewise constant cell values. The velocities are calculated as

\[ \boldsymbol v_\alpha = - \lambda_\alpha \boldsymbol K \textbf{grad}\, \Phi_\alpha, \]

and,

\[ \boldsymbol v_t = \boldsymbol v_w + \boldsymbol v_n,\]

where \( \Phi_\alpha \) denotes the potential of phase \( \alpha \), \( \boldsymbol K \) the intrinsic permeability, and \( \lambda_\alpha \) a phase mobility.

Remark1: only for 2-D quadrilateral grids!

◆ addOutputVtkFields()

template<class TypeTag >
template<class MultiWriter >
void Dumux::FvMpfaO2dVelocity2P< TypeTag >::addOutputVtkFields ( MultiWriter &  writer)
inline

Adds velocity output to the output file.

Adds the phase velocities or a total velocity (depending on the formulation) to the output. If the VtkOutputLevel is equal to zero (default) only primary variables are written, if it is larger than zero also secondary variables are written.

Template Parameters

Parameters
writerThe output writer (usually a VTKMultiWriter object)
