Overview
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.
Unreal Engine
Unreal Engine provides you with a complete suite of creation tools for developing real-time 3D content. Whether you are building a high-fidelity AAA game, a cinematic film, or a complex architectural visualization, you can manage the entire production pipeline within a single environment. You get access to a powerful world-builder, advanced lighting systems, and a robust physics engine that brings your creative visions to life with stunning realism.
The platform is designed to scale with your ambitions, offering a flexible environment that supports everything from solo indie projects to massive enterprise simulations. You can take advantage of the source code access to customize the engine to your specific needs. With a vast marketplace of assets and a global community of creators, you have the resources necessary to solve complex development challenges and accelerate your project timelines.
