Does anyone know if the MKL Fast Poisson Solver can be used for the nonlinear Poisson eqn?

Hello,

Is it possible to modify the Intel MKL Fast Poisson Solver for the problem of type:

Δ .[K(u). Δ(u) ] = f 

where Δ is the gradient symbol (I didn't find the reverse triangle in the special characters). K(u) is a positive differentiable function dependent on the position. Check the equation here:

The difference between the above equation and the demonstrated Poisson eqn. at MKL Poisson solver page is the term K(u).

this question is related to intel mkl library but not intel DAAL.

just forget to add the link to the mkl forum -- https://software.intel.com/en-us/forums/intel-math-kernel-library
