Model SINDA/FLUINT - Heat Transfer and Fluid Modeling Software

For decades, SINDA/FLUINT has provided users with proven and powerful heat transfer and fluids analysis capabilities that continue to expand each year. SINDA/FLUINT is a comprehensive, generalized tool for simulating complex thermal/fluid systems such as those found in the electronics, automotive, petrochemical, power generation, medical, and aerospace industries. SINDA/FLUINT saves time and money by making the design process faster and easier, letting you gain a better understanding of your complex system. You control what is important and how to get the answer to your design performance questions using the most efficient approach. Furthermore, the application is completely extensible making it perhaps the most versatile thermal and fluids software product on the market. You choose the features you want, decide what levels of accuracy and approximation are appropriate, and what outputs are needed. You can even add your own customizations as needed to handle your unique design task, to automate repetitive tasks, or to create user-defined modeling components and correlation libraries.

As you can see in the above diagram, SINDA/FLUINT is the solution engine behind Thermal Desktop® and its various modules. Alternatively, SINDA/FLUINT can be used in a text-based mode applying the COM-based API interface with Mathworks` MATLAB® or other COM-aware applications. More often, however, those APIs are used to communicate with Thermal Desktop directly.
