FlowVision CFD

FlowVision is a multiphysics CFD tool for simulating 3D laminar and turbulent flows - steady or unsteady - of liquids and gases. It uses the finite volume method, high-accuracy difference schemes, and robust models to handle complex phenomena like swirling flows, moving free/contact surfaces, shock waves, conjugate heat transfer, and combustion.

FlowVision employs a Cartesian, locally adaptive grid that dynamically refines based on user-defined criteria. Geometry is represented via Boolean subtraction of non-computed volumes, producing polygonal cells of arbitrary shape without simplifying boundary cells. Grid generation is fully automatic.

The software supports mixed parallelization - MPI across nodes and threading within nodes - allowing excellent scaling on high-performance systems. 

FlowVision supports flow simulations around moving or deforming bodies through coupling with finite element tools like Abaqus, making it a go-to choice for complex FSI simulations.
