Hi. I don't know if this is the correct place to ask this, but prefer you to suggest me where I should ask. I'm starting with numerical simulation and I've been playing with the finite differences method to solve the heat equation on 1D, 2D and 3D uniform grids. This was really simple. Now I want to introduce some thermal insulator elements in my simulation, let's say I have a 2D rectangular surface with some squared thermal insulators embedded in it. What should I do with the nodes that are located in the insulator region? How should I calculate them? Maybe it's a really simple problem, but it's been puzzling me for some time now and I don't know where should I start looking for an answer.(adsbygoogle = window.adsbygoogle || []).push({});

Thanks in advance,

Federico
