HIGH-QUALITY CFD BASED ON THE BOLTSMAN LATTICE METHOD
When solving CFD problems involving unsteady flow, which often arise due to the flow around solid bodies with complex geometries, such as the outer surface of a car, the traditional mesh-based approach to solving these problems is highly dependent on the quality of the mesh. This results in engineers spending most of their time on mesh discretization rather than solving the engineering problem. In addition, difficulties can arise when changing the topology of the domain for problems involving moving parts or fluid-structure interaction.
XFlow offers particle-based Boltzmann grid technology for high-fidelity computational fluid dynamics (CFD) applications, expanding the SIMULIA CFD portfolio. XFlow's advanced technology enables users to solve complex CFD workflows, including high-frequency unsteady aerodynamics with real moving geometry, complex multiphase flows, free-surface flows, and fluid-structure interactions.
XFlow's automatic meshing and adaptive refinement capabilities minimize user input, reducing the time and effort required for meshing and pre-processing in a typical CFD workflow. This allows engineers to focus most of their efforts on design iteration and optimization rather than the labor-intensive process of mesh generation.
When using the XFlow approach to discretization, surface complexity is also not a limiting factor. The underlying mesh can be controlled with a small set of parameters; the mesh is tolerant to the quality of the input geometry and adapts to the presence of moving parts.
In addition, advanced rendering capabilities provide realistic visualization for a deeper understanding of flow and thermal characteristics. XFlow's unique capabilities enable companies to reduce the number of physical tests and accelerate the adoption of better design decisions.
