Hi...
.I work on pcm simulation and now try to add the nucleation process.I use the classical nucleation theory and now I need to calculate the crystallization probability so as to achieve percolation.I need to calculate the growth probability for a grid according to its four nearest neighbours..I try to add a summation for P_N=sum(P_f*delta_(1,P_f))P;_N shows a summation over the next neighbors and P_f gives crystallization probability.My problem is how to write the summation in three dimension in comsol.

I know the number of grids so the summation is not an infinite one but I need to consider the growth probability in three dimension.

Thanks for your consideration...
