How to implement anisotropic diffusion coefficient
 
Hi, can somebody point me to an example of how to implement an anisotropic diffusion coefficient? For example, on a 2D geometry, I want the x-direction diffusion coefficient to be smaller than the y-direction diffusion coefficient.

You can pass a tensor as "coefficient" to the laplacian.

Best,
