This is a 3D Thermal Mathematical Model Builder working on PC and works as an expanded module of AutoCAD®. The operability is almost equivalent to AutoCAD®, and models can be created by simply selecting primitive elements, such as various surfaces and solids, and clicking points of grids.

SINDA/FLUINT is an all-purpose thermal-fluid analysis system integrating SINDA, a thermal analysis solver, and FLUINT, a fluid analysis solver. Though, this can be used as stand-alone system, systematic simulation including geometry models can also be possibly integrated with Thermal Desktop®.

FloCAD® is 1D fluid analysis module working with Thermal Desktop®, and can create hybrid models where normal heat transfer and thermal fluid are mixed. With the same concept and operation as geometry models created by Thermal Desktop®, fluid models can be created and added at GUI.

RadCAD® is a calculation module of radiation working with Thermal Destop®. RadCAD® calculations are made using the Ray tracing method using Monte Carlo method, and configuration factor, radiation conductance, on-orbit thermal input and others, which is in accordance with input format of SINDA/F.

Sinaps is a GUI tool having an environment for 2D drawing, for SINDA/F. Since Sinaps has pre or post processing functions for thermal network modeling, text based SINDA/FLUNIT input files can be opened by this software.
