class	PorousFlowDarcyVelocityComponentLowerDimensional
	Computes a component of the Darcy velocity: -k_ij * krel /(mu a) (nabla_j P - w_j) where k_ij is the permeability tensor, krel is the relative permeaility, mu is the fluid viscosity, a is the fracture aperture, P is the fluid pressure and w_j is the fluid weight tensor that is projected in the tangent direction of this element This is measured in m^3 .

      "Darcy velocity on a lower-dimensional element embedded in a higher-dimensional mesh.  Units "
      "m^3.s^-1.m^-2, or m.s^-1.  Darcy velocity =  -(k_ij * krel /(mu * a) (nabla_j P - w_j)), "
      "where k_ij is the permeability tensor, krel is the relative permeability, mu is the fluid "
      "viscosity, P is the fluid pressure, a is the fracture aperture and w_j is the fluid weight. "
      " The difference between this AuxKernel and PorousFlowDarcyVelocity is that this one "
      "projects gravity along the element's tangent direction.  NOTE!  For a meaningful answer, "
      "your permeability tensor must NOT contain terms that rotate tangential vectors to "
      "non-tangential vectors.");
