Common base class to all handles. Stores arrays of the matrices involved in the interaction volume-local systems of equations. Apart from the transmissibility matrix we store those matrices that are needed e.g. for later face pressure reconstruction. The fluxes as well as the local systems of equations can be expressed as functions of the intermediate unknown face face values $\bar{\mathbf{u}}$ and the known cell/Dirichlet values $\mathbf{u}$ using the matrices $\mathbf{A}$ , $\mathbf{B}$ , $\mathbf{C}$ , $\mathbf{D}$ and the vector of Neumann fluxes $\mathbf{N}$ as follows: More...

class Dumux::CCMpfaDataHandleBases::SystemMatricesHandle< MVT, size1, size2 >

Common base class to all handles. Stores arrays of the matrices involved in the interaction volume-local systems of equations. Apart from the transmissibility matrix we store those matrices that are needed e.g. for later face pressure reconstruction. The fluxes as well as the local systems of equations can be expressed as functions of the intermediate unknown face face values $\bar{\mathbf{u}}$ and the known cell/Dirichlet values $\mathbf{u}$ using the matrices $\mathbf{A}$ , $\mathbf{B}$ , $\mathbf{C}$ , $\mathbf{D}$ and the vector of Neumann fluxes $\mathbf{N}$ as follows:

Fluxes: $\mathbf{f} = \mathbf{C}\bar{\mathbf{u}} + \mathbf{D}\mathbf{u}$ Local eq system: $\mathbf{A}\bar{\mathbf{u}} = \mathbf{B}\mathbf{u} + \mathbf{N}$
