I have attached a code below I am trying to plot the real value of the fourier component of electric field dq l, and I am taking contribution of fields from all positions dx j.
When I ListPlot3D for nn=200, the Mathematica quits its kernel by itself without any error or warning. I wonder is it the memory issue or something else because the code works well for few points such as nn=20. But I have to have nn=200.
