FVAnisotropicDiffusion
Computes residual for anisotropic diffusion operator for finite volume method.
An anisotropic diffusion term that is discretized using the finite-volume method:
where is the diagonal tensor diffusion coefficient and is the diffusing variable. The discretized form of the equation above over en element is the following:
where denotes the surface vector of face of the element. Furthermore, the face gradient, (\nabla \phi)_f, is determined using a central difference scheme combined with non-orthogonal correction. Lastly, components of the diffusion (diagonal) tensor can be either interpolated to the face using a geometric arithmetic average:
or a harmonic average:
where is the interpolation weight, and subscripts and represent element and neighbor values.
