The Thermal Systems Analysis Toolbox (TSAT) is a MATLAB/Simulink based tool for modeling and analysis of dynamic thermal systems involving heat transfer. It is best suited for 1-D and 2-D heat transfer involving solid planar and cylindrical structures, however, the toolset is more extensive than this. The tools enable consideration of conduction, convection, and radiation boundary conditions. Some advanced capabilities are provided when it comes to approximating conduction within non-isotropic materials, structures with material transitions, and structures with time-varying temperature dependent material properties. Numerous tools are available to facilitate the construction of modular models of thermal systems and their integration with larger system models. - View it on GitHub
