PorousFlowFluidPropertyIC

An initial condition to calculate one fluid property (such as enthalpy) from pressure and temperature

This initial condition provides a straightforward way to specify an initial value for a fluid property using pressure and temperature as the inputs.

A valid Fluid Properties UserObject is required.

note

The FluidProperties UserObject expects temperature in Kelvin. If the simulation uses temperature in Celsius, temperature_units = celsius must be used.
