Yeah, that was my problem. After 150 terms there were excellent results.

For two reasons: 1. Numerical solution near edges is close to 20*C 2. Initial condition is 20*C for x belongs to (0,L)

Hi, thanks u for reply. I am not sure how showing my MATLAB code could help here. I checked several times if i correctly applied the formula. My problem is rather the formula that i derived analytically. When i put solution to equation it satisfies it. But when i just put t=0 to solution i...

Hi, I am solving heat equation with internal heat sources both numerically and analytically. My graphs are nearly identical but! analytical one have problem at the beginning and at the end for my domain. Many people have used the same technique to solve it analytically and they got good answers...
