FlowVision Fluid Dynamics Analysis Software - 3D Fluid Flow and Heat Transfer Simulation

Introduction to FlowVision software

FlowVision was developed in 1991 at the Royal Institute of Physics and Engineering (MIPD) in Moscow by dozens of senior researchers as one of the main solution tools of the National Key Scientific Program. It was later officially launched as a commercial software package in 1994, and has a history of nearly two decades. At present, it is a set of CFD simulation software widely used in advanced countries such as Europe and the United States, which can solve various complex three-dimensional fluid flow, heat and mass transfer problems. The FlowVision solver uses the finite volume method and a robust physical model, applying 32-bit and 128-bit parallel algorithms with high accuracy and high efficiency. FlowVision fully integrates pre-processing, solver, and post-processing into a single software interface for easy user operation. CAD and FEM models of any complex 3D model, parts and assemblies (ANSYS, ABAQUA, NASTRAN）。 FlowVision uses a non-fitted Cartesian mesh-based finite volume method with the world's leading sub-grid geometry reconstruction (SGGR) sub-grid-geometry-resolutionThe mesh technology can completely maintain the curvature of the original boundary under a coarse mesh, make it easier to distinguish the fluid domain from the solid domain, and automatically establish a wetted interface, which can deal with the dynamic boundary and boundary deformation of any complex object. It supports real-time display of calculation, monitoring and post-processing, and users can add or remove post-processing operations at any time during the simulation and analysis process, which greatly enhances the analysis ability. The FlowVision software's solver can run on remote multiprocessor fleets for efficient parallel analysis, and can also be used by multiple users for easy use by the same group. FlowVision can be combined with ABAQUS to solve complex fluid-structure interaction problems, with high efficiency and more accurate computing capabilities. Direct bidirectional flow direction coupling is realized by MPM (Multi-Physics-Manager) control FlowVision and ABAQUS software. There is no need for third-party data exchange software and no interpolation math errors. FlowVision also provides multiphysics coupling analysis with other software, such as LMS Virtual Lab.Acoustics aerodynamic noise analysis, TORT flow field optical propagation coupling analysis, SIGMA Technology IOSO Multi-objective Optimization Analysis.
