NumbatDarcyVelocity
Calculates Darcy velocity
An AuxKernel to calculate the fluid velocity given by Darcy's law (1) where is the permeability, is the fluid viscosity, is the fluid pressure, is the fluid density (as a function of concentration) and is gravity.
As an AuxKernel can only calculate a scalar, the component of the fluid velocity must be specified

- use_displaced_meshFalseWhether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.Default:False C++ Type:bool Description:Whether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.
