The ability to quickly calculate hydraulic conductivity, mass transfer coefficient, and heat transfer rate using an input file generated from a 3D CAD model. It's also very easy to use with the help of the user manual. I do not have any dislikes about this software product. I can highly recommend it to other engineers who require rapid calculations of thermal and hydraulic properties of a fluid flow system. This software is very useful as it helps in reducing time taken for the calculation of flow rates and thermal properties of fluid flows.
