2D heat conduction of layered composite model

[geetar_king]

Hi, I am trying to formulate a 2D model to calculate the temperature change over time in a composite material.

The material consists of several layers, and is heated from all edges by a known temperature vs time profile.

I was thinking of creating a finite element model.

Can someone point me to a similar example? I have done 1D conduction model before but always with a homogeneous material. Do I just have to create nodes throughout and assign different material properties to each?

I have attached a schematic of what I am trying to describe.

Thanks

To do the problem as you've defined it, then yes, you have to do it pretty much the way you described. I would be more inclined to use finite difference than finite element.

Thanks Chet, I will give it a try with finite difference method.
