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.
