Hello Tarik,

You typically call an interpolation function of x and y.
The example "aquifer characterization" from the Subsurface Flow module is the closest COMSOL has for imposing a function that is mesh dependent like yours.

The principle of using interpolation function is used in the simpler "rock fracture flow" available with the basic package. Note that in such case the function is not mesh-dependent.

I'll send you a bit more details elsewhere.
Good luck,
Eric
