I wrote a 3D steady state solver for the fourier heat equation in Matlab. The geometries are input as STL files which are converted to 3D matrices of thermal conductivity values. The solver produces a matrix of temperatures which can be scatter plotted or color mapped on to the input STL file surface.

I used this solver to simulate my chip furnace which can be found here.​
