FINETM/Open is a powerful CFD Flow Integrated Environment dedicated to complex internal and external flows. It combines completely unstructured hexahedral grids with an efficient preconditioned compressible solver with fast agglomerated multigrid acceleration and adaptation techniques. This makes the product unique in the CFD community. FINE/Open offers solution adaptive grids. Features Unique meshing speed. HEXPRESSTM is an advanced and powerful unstructured grid generator for complex geometries. It constructs fully hexahedral, high quality meshes in hours instead of weeks; Full compatibility with AutoGridTM block structured meshes for complex geometries, including rotating machineries; Fully hexahedral unstructured technology for higher accuracy, robustness, and reliability; Single solver with extended fluid capabilities, from incompressible low speed to the compressible hypersonic flow regime; Fast convergence acceleration through an unique multigrid technology based on agglomerated cells; Solution based adaptation with iterative grid coarsening and refinement based on physical sensors; Fast thermal engine for large scale conjugate heat transfer prediction; Easy-to-use wizard based interface that guides the user through the meshing process, flow case set-up, launching, and convergence monitoring with a constant geometry display; Automated and integrated post-processing, CFViewTM.
