VolumetricFlowRate
Computes the volumetric flow rate of an advected quantity through a sideset.
Example input syntax
In this example, we measure:
the mass flow rate
the momentum flow rate
the enthalpy flow rate
with numerous VolumetricFlowRate postprocessors to prove the conservation of mass, momentum and energy of the finite volume discretization of the incompressible Navier Stokes equations.
