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.
QBlade
QBlade gives you a powerful, open-source environment to design and simulate wind turbines from the ground up. You can create custom airfoil data, integrate them into rotor blades, and perform complex aero-elastic simulations to see how your designs handle real-world conditions. It simplifies the transition from initial blade geometry to full-system performance testing within a single graphical interface.
You can use it for both horizontal and vertical axis wind turbines, making it a versatile choice for researchers, students, and engineers in the renewable energy sector. By providing tools for structural modal analysis and turbulent inflow generation, it helps you identify potential failure points and efficiency gains before moving to physical prototyping.
