hi everyone,

I have a problem. I would like to compute the gradient of a scalar C(x,y) with SPH.

in Liux book is reported that:

\nabla A = \sum (A_I+A_J) \nabla \phi_{IJ} \Delta V


The question is how can I deal with the Kernel functions?

I mean. If the test function is W(r) how can derive in x and y?

thank you very much
