Description

template<class TypeTag>
class Dumux::EvalCflFlux< TypeTag >

Base class for implementations of different kinds of fluxes to evaluate a CFL-Condition.

Base class for implementations of different kinds of fluxes to evaluate a CFL-Condition of the form

\[ \frac{F_i \Delta t}{V_{p_i}} < 1 \]

where \( V_{p_i} \) is the pore volume of cell i and

\[ F_i = \sum f_{ij} \]

with \( f_{ij} \) being the CFL-flux over edge \( ij \).
