FINE™/Turbo is the fastest CFD suite for rotating machinery with incompressible and compressible fluids, from subsonic to hypersonic flow regimes. All types of multi-stage axial, radial or mixed-flow configurations are supported: compressors, turbines, pumps, fans, propellers or contra-rotating propellers. From meshing to results visualization, the FINE™/Turbo application-oriented graphical user interface is intuitive, enabling fast project set-up and analysis. The simulation process is streamlined with:

  1. AutoGrid5™: Automated grid generator for turbomachinery configuration, delivers the highest quality structured meshes with minimum user input. Its Wizard mode handles all types of rotating machinery configurations and complexities.
  2. FINE™/Turbo flow solver: 3D Navier-Stokes flow solver, recognized as the fastest and most accurate for turbomachinery configurations. Acceleration of several orders of magnitude is achieved thanks to the CPUBooster™ technique, NLH approach and HPC scalability. 
  3. CFView™: Advanced post-processing tool, provides dedicated flow visualization and analysis outputs in an easy-to-use turbomachinery-oriented mode.

Key Features
