| May 26, 2011 at 14:06 | comment | added | Patrick | I edited my question to (hopefully) clarify what I'm asking. I expect to need to solve the problem numerically, but I'm not sure how to formulate the problem to do so. I realize the time term vanishes as t goes to infinity, but I would like to include it if possible. | |
| May 26, 2011 at 4:31 | comment | added | Omega Centauri | Last time I had a 2D thermal problem, I wanted to match Greens functions on the various boundaries, but that is tricky (algebra and programming wise), i.e. the chance of a coding blunder was too great. Since modern computers are amazingly fast brute force machines successive relaxation on a grid is so trivial to program you almost can't mess it up, and solution time is quite minimal. | |
