Description

template<class TypeTag>
class Dumux::MimeticPressure2P< TypeTag >

Mimetic method for the pressure equation.

Provides a mimetic implementation for the evaluation of equations of the form

$$\text{div}\, \boldsymbol{v}_{total} = q.$$

The definition of the total velocity $\boldsymbol{v}_total$ depends on the kind of pressure chosen. This could be a wetting (w) phase pressure leading to

$$- \text{div}\, \left[\lambda \boldsymbol{K} \left(\text{grad}\, p_w + f_n \text{grad}\, p_c + \sum f_\alpha \rho_\alpha g \text{grad}\, z\right)\right] = q,$$

a non-wetting (n) phase pressure yielding

$$- \text{div}\, \left[\lambda \boldsymbol{K} \left(\text{grad}\, p_n - f_w \text{grad}\, p_c + \sum f_\alpha \rho_\alpha g \text{grad}\, z\right)\right] = q,$$

or a global pressure leading to

$$- \text{div}\, \left[\lambda \boldsymbol{K} \left(\text{grad}\, p_{global} + \sum f_\alpha \rho_\alpha g \text{grad}\, z\right)\right] = q.$$

Here, $p$ denotes a pressure, $\boldsymbol{K}$ the absolute permeability, $\lambda$ the total mobility, possibly depending on the saturation, $f$ the fractional flow function of a phase, $\rho$ a phase density, $g$ the gravity constant and $q$ the source term. For all cases, $p = p_D$ on $\Gamma_{Neumann}$, and $\boldsymbol{v}_{total} = q_N$ on $\Gamma_{Dirichlet}$.
