  • MovingPlanarFrontThis function defines the position of a moving front. The front is an infinite plane with normal pointing from start_posn to end_posn. The front's distance from start_posn is defined by 'distance', so if the 'distance' function is time dependent, the front's position will change with time. Roughly speaking, the function returns true_value for points lying in between start_posn and start_posn + distance. Precisely speaking, two planes are constructed, both with normal pointing from start_posn to end_posn. The first plane passes through start_posn; the second plane passes through end_posn. Given a point p and time t, this function returns false_value if ANY of the following are true: (a) t<activation_time; (b) t>=deactivation_time; (c) p is 'behind' start_posn (ie, p lies on one side of the start_posn plane and end_posn lies on the other side); (d) p is 'ahead' of the front (ie, p lies one one side of the front and start_posn lies on the other side); (e) the distance between p and the front is greater than active_length. Otherwise, the point is 'in the active zone' and the function returns true_value.

PorousFlowBasicTHM

  • Porous Flow App
  • PorousFlowBasicTHMAdds Kernels and fluid-property Materials necessary to simulate a single-phase, single-component fully-saturated flow problem. No upwinding and no mass lumping of the fluid mass are used. The fluid-mass time derivative is close to linear, and is perfectly linear if multiply_by_density=false. These features mean the results may differ slightly from the Unsaturated Action case. To run a simulation you will also need to provide various other Materials for each mesh block, depending on your simulation type, viz: permeability, constant Biot modulus, constant thermal expansion coefficient, porosity, elasticity tensor, strain calculator, stress calculator, matrix internal energy, thermal conductivity, diffusivity

PorousFlowFullySaturated

  • Porous Flow App
  • PorousFlowFullySaturatedAdds Kernels and fluid-property Materials necessary to simulate a single-phase fully-saturated flow problem. Full-upwinding of fluid flow is not available in this Action, so the results may differ slightly from the Unsaturated Action. However KT stabilization may be employed for both the fluid and any heat flow. 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

PorousFlowUnsaturated

  • Porous Flow App
  • PorousFlowUnsaturatedAdds Kernels and fluid-property Materials necessary to simulate a single-phase saturated-unsaturated flow problem. The saturation is computed using van Genuchten's expression. 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
