DiracKernels System

under construction:Undocumented System

The DiracKernels system has not been documented. The content listed below should be used as a starting point for documenting the system, which includes the typical automatic documentation associated with a system; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.

  • PorousFlowPeacemanBoreholeApproximates a borehole in the mesh using the Peaceman approach, ie using a number of point sinks with given radii whose positions are read from a file. NOTE: if you are using PorousFlowPorosity that depends on volumetric strain, you should set strain_at_nearest_qp=true in your GlobalParams, to ensure the nodal Porosity Material uses the volumetric strain at the Dirac quadpoints, and can therefore be computed
  • PorousFlowPolyLineSinkApproximates a polyline sink by using a number of point sinks with given weighting whose positions are read from a file. NOTE: if you are using PorousFlowPorosity that depends on volumetric strain, you should set strain_at_nearest_qp=true in your GlobalParams, to ensure the nodal Porosity Material uses the volumetric strain at the Dirac quadpoints, and can therefore be computed
  • PorousFlowSquarePulsePointSourcePoint source (or sink) that adds (removes) fluid at a constant mass flux rate for times between the specified start and end times.
