Overview
CONVERGE CFD
CONVERGE CFD changes how you approach fluid dynamics by removing the most time-consuming part of the simulation process: manual meshing. Instead of spending days or weeks refining grids, you can rely on its autonomous meshing capabilities to create the mesh at runtime. This allows you to simulate complex moving geometries and intricate flow patterns with high accuracy and significantly reduced setup time.
You can apply this tool across various industries, from internal combustion engines and gas turbines to pump design and medical devices. The software excels at handling transient simulations where boundaries move or change shape, ensuring your mesh always adapts to the physics of the problem. By automating the grid generation, you can focus your energy on analyzing results and optimizing your designs rather than troubleshooting mesh quality.
SIMULIA XFlow
SIMULIA XFlow offers a unique approach to computational fluid dynamics (CFD) by using a particle-based Lattice-Boltzmann method. This allows you to skip the traditional, time-consuming meshing process and move straight into simulating complex moving geometries or multiphase flows. You can accurately predict aerodynamic performance, free-surface flows, and fluid-structure interactions without the numerical instability often found in grid-based solvers.
The platform is designed for engineers in high-stakes industries like aerospace, automotive, and energy where transient effects are critical. You can simulate everything from vehicle water wading and cabin climate control to aircraft landing gear deployment. By reducing the manual effort required for geometry preparation, you can run more design iterations in less time and improve the overall performance of your physical products.
