I am solving a simple classical diffusion equation for 'c' with the diffusion coefficient being directional dependent (function of grad(c)). I am getting some weird results and numerical noise for the diffusion coefficient as it is being calculated.

Can anyone that has possibly had this issue please aide me in possibly fixing this issue. I have attached the simple model file to examine.

Thank you​
