PorousFlowPointSourceFromPostprocessor
PorousFlowPointSourceFromPostprocessor implements a mass point source that adds (or removes) fluid at a mass flux rate that was computed by a postprocessor.
For instance:
[DiracKernels]
[source]
type = PorousFlowPointSourceFromPostprocessor
variable = pp
mass_flux = mass_flux_in
point = '0.5 0.5 0'
[]
[]
Note that the execute_on parameter is set to timestep_begin so that the correct value is being used within the timestep.
[Postprocessors]
[total_mass]
type = PorousFlowFluidMass
execute_on = 'initial timestep_end'
[]
[mass_flux_in]
type = FunctionValuePostprocessor
function = mass_flux_fn
execute_on = 'initial timestep_begin'
[]
[]

# - Celsius instead of Kelvin
# - no use of PorousFlowPointEnthalpySourceFromPostprocessor since that is not yet merged into MOOSE: a DirichletBC is used instead
# - Use of PorousFlowFullySaturated instead of PorousFlowUnsaturated, and the save_component_rate_in feature to record the change in kg of each species at each node for passing to the Geochem simulation

# Test that PorousFlowHysteresisOrder correctly calculates hysteresis order
# Hysteresis order is initialised = 3, with turning points = (0.5, 0.8, 0.66)
# Initial saturation is 0.71
# A large amount of water is removed in one timestep so the saturation becomes 0.58 (and order = 0)
# Then, water is added to the system (order = 1, with turning point = 0.58) until saturation = 0.67
# Then, a large amount of water is removed from the system so order becomes 0
