Best-in-class turbomachinery design tools
Engineers looking to combine speed and accuracy for their virtual turbomachinery designs trust NUMECA for their toughest challenges. We have designed a unique toolset that encompasses a complete end-to-end solution: 1D to 3D, Meshing, CFD and Optimization, all in one single environment. Thanks to more than 75 years of expertise in rotating machinery, the environment displays an unsurpassed ease-of-use and accuracy.

Configurations range from multi-stage axial to radial to mixed-flow configurations (compressors, turbines, pumps, fans, propellers or contra-rotating propellers).
