Description

template<class TypeTag>
class Dumux::FvMpfaL2dPressureVelocity2pAdaptive< TypeTag >

Class for the calculation of velocities from the pressure solution of an IMPES scheme using a grid adaptive MPFA L-method.

Can be used for calculating the complete velocity field before the solution of the transport equation (more efficient), or for face-wise velocity calculation directly in the transport solution (less efficient).

Remark1: only for 2-D quadrilateral grids!

Remark2: can use UGGrid, ALUGrid

Remark3: Allowed difference in grid levels of two neighboring cells: 1
