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.
PVsyst
PVsyst is a technical modeling tool designed to help you predict the energy yield of solar photovoltaic systems. You can import meteorological data from various sources and define specific system components like modules, inverters, and cabling to create a highly accurate digital twin of your project. The software handles everything from small residential setups to massive utility-scale power plants, providing you with the detailed reports needed for financial planning and technical validation.
You can perform complex shading analysis using a 3D CAD environment to see exactly how nearby objects impact your energy production. It allows you to account for thermal losses, horizon shading, and spectral effects to ensure your simulations match real-world performance. Whether you are an engineer designing a grid-connected system or a researcher studying stand-alone installations, you get the precision required for bankable solar energy assessments.
