Abstract

Engineers rely on a wide variety of modern thermal tools to model thermal problems; many of these tools offer graphical “front ends” whereby users formulate their analytical models using a CAD interface. Behind the scenes, the analysis is performed on a thermal network – this is true whether the analyst uses finite differencing or finite element methodologies. While graphical front ends are very powerful, understanding the resulting thermal network representation used for a model gives the user the ability to check or even modify the models at a basic level. Additionally, there are instances where an engineer may prefer to develop network models from scratch or use heritage code that does not have a graphical front end. Some front-end programs output thermal networks in the widely used SINDA format; our lesson will focus on this input format.
