Turbomachinery CFD - TCFD. Turbomachinery CFD (TCFD®) is the CFD software package and workflow for all standard rotating machinery. It is the final outcome of many years of development of CFD support team of engineers and developers. Turbomachinery CFD was created to enable a quick and efficient design simulation and optimization of turbomachinery components. TCFD® workflow covers complete process, from basic (usually CAD) data, over the CFD analysis, to the significant engineering results. TCFD® numerical solver is based on OpenFOAM®. TCFD® is not dependent on other software but it is fully compatible with standard OpenFOAM® and other software packages. It was originally designed for simulating rotational machines, nevertheless it can be used for a wide range of various CFD simulations.
