Innovation & Quality


FINE/Marine is an integrated CFD software environment for the simulation of mono-fluid and multi-fluid flows around any kind of ships, boats or yachts, including various types of appendages. The powerful and customized graphical user interface drives the user into the whole simulation process and integrates marine-dedicated features with: 

  • HEXPRESS, our highly automated mesh generator for high quality and full hexahedral unstructured meshes;
  • FINE™/Marine's flow solver, our 6DOF incompressible flow solver, recognized as having the best accuracy for all types of marine applications, including free surface capturing. The FINE™/Marine's flow solver is developed by the “Ecole Centrale de Nantes” (ECN) and CRNS and industrialized in partnership with NUMECA.
  • CFView, our powerful post-processing and scientific visualization system offering all qualitative and quantitative tools and marine dedicated add-ons for flow visualization and analysis.
