LinearFrictionFactorFunctorMaterial

This class allows to compute the friction coefficient $W$ that is used as:

-\epsilon \nabla p = W \rho \vec{v}_I

in the porous flow equations where all symbols have their common meaning (see porous media equations) and we do not write all the other momentum equation terms. The friction factor is a diagonal tensor computed by:

\vec{W} = \vec{A} f(\vec{r}, t) + \vec{B} g(\vec{r}, t) \| \vec{v}_I\|,

where $\vec{A}$ and $\vec{B}$ are constant vectors provided by the user, $f$ and $g$ are scalar functors.

constant_onNONEWhen ELEMENT, MOOSE will only call computeQpProperties() for the 0th quadrature point, and then copy that value to the other qps.When SUBDOMAIN, MOOSE will only call computeQpProperties() for the 0th quadrature point, and then copy that value to the other qps. Evaluations on element qps will be skipped
Default:NONE

Evaluations on element qps will be skipped
declare_suffixAn optional suffix parameter that can be appended to any declared properties. The suffix will be prepended with a '_' character.
