Sauna at a glance
 created for the thermal simulation of electronic equipment
 used to model heat sinks, circuit boards (PCB's) and boxes (with
and without internal PCB's)
 models are composed of the building blocks of plates and
boards
 underlying modeling method is thermal network (thermal nodes and
resistors), but modern architecture means that user rarely specifies
a resistor value
 large component library
 convection and radiation coefficients calculated automatically
 easy to learn and use, much easier than finite
element method (FEM) or computational fluid dynamics (CFD)
