Question: Problem with 3dplot - function doesn't show when increasing summation limit

Question:Problem with 3dplot - function doesn't show when increasing summation limit

Hi

I have the function of x and y

10*sinh(n*Pi*(L-y)/L)*sin(n*Pi*x/L)*(2*(1+(-1)^(n+1)))/(sinh(n*Pi)*n*Pi)

with n summed up from 1 to an integer - say 100 (couldn't get the summation sign in here). When plotting this function with plot3d it works just fine with 100 as the summation limit. The problem is, when I increase the limit to say 500, a part of the graph (the part with a value above approximately 1.8 doesn't show up)., 

Any ideas on how to fix this?

Thanks in advance.
