MaterialPropertyLib::VermaPruessModel Class Reference

Detailed Description

Verma-Pruess equation [42].

$$k = k_0 \left( \frac{\phi - \phi_c}{\phi_0 - \phi_c} \right)^n,$$

where $k$ is the permeability, $k_0$ is the initial permeability, $\phi$ is the porosity, $\phi_0$ is the initial porosity, $\phi_c$ is the critical porosity, and $n$ is the exponent.

overridevirtual

This virtual method will compute the property value based on the variables that are passed as arguments with the default implementation using empty variables array for the previous time step.

Reimplemented from MaterialPropertyLib::Property.
