PorousFlowFullySaturated

under construction:Undocumented Class

The PorousFlowFullySaturated has not been documented, if you would like to contribute to MOOSE by writing documentation, please see Documenting MOOSE. The content contained on this page explains the typical documentation associated with an action; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.

Adds Kernels and fluid-property Materials necessary to simulate a single-phase fully-saturated flow problem. No upwinding of fluid flow is used, so the results may differ slightly from the Unsaturated Action. No Kernels for diffusion and dispersion of fluid components are added. To run a simulation you will also need to provide various other Materials for each mesh block, depending on your simulation type, viz: permeability, porosity, elasticity tensor, strain calculator, stress calculator, matrix internal energy, thermal conductivity, diffusivity

  • mass_fraction_varsList of variables that represent the mass fractions. With only one fluid component, this may be left empty. With N fluid components, the format is 'f_0 f_1 f_2 ... f_(N-1)'. That is, the N^th component need not be specified because f_N = 1 - (f_0 + f_1 + ... + f_(N-1)). It is best numerically to choose the N-1 mass fraction variables so that they represent the fluid components with small concentrations. This Action will associated the i^th mass fraction variable to the equation for the i^th fluid component, and the pressure variable to the N^th fluid component.
