Description

template<class TypeTag>
class Dumux::FVPressureVelocity1P< TypeTag >

Single Phase Finite Volume Model.

This model solves equations of the form

\[ \textbf{div}\, \boldsymbol v = q. \]

The velocity \( \boldsymbol v \) is the single phase Darcy velocity:

\[ \boldsymbol v = -\frac{1}{\mu} \boldsymbol K \left(\textbf{grad}\, p + \rho \, g \, \textbf{grad}\, z\right), \]

where \( p \) is the pressure, \( \boldsymbol K \) the absolute permeability, \( \mu \) the viscosity, \( \rho \) the density, and \( g \) the gravity constant, and \( q \) is the source term. At the boundary, \( p = p_D \) on \( \Gamma_{Dirichlet} \), and \( \boldsymbol v \cdot \boldsymbol n = q_N\) on \( \Gamma_{Neumann} \).
