TAS is a system designed to computer simulate nearly any thermal problem you have.

Problems are simulated geometrically using 2D Plate and 3D Brick and Tetrahedron elements. TAS can accurately represent skewed elements. TAS uses a Finite Element method to convert geometry into an accurate resistor/capacitor representation which is then accurately and quickly solved using a finite difference or Conjugate Gradient method. This combination gives accurate results like other Finite Element (FEA) solver and provides you with unsurpassed flexibility in model generation. There are no limits to model size, only limited to PC memory.
