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.
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.
