Overview
Altair SimLab
Altair SimLab is a multidisciplinary simulation environment designed to help you automate the setup of complex engineering analyses. Instead of manually creating meshes for every part, you can use feature-based modeling to automatically recognize CAD geometry like holes, fillets, and ribs. This allows you to move from raw CAD data to a functional simulation model in minutes rather than hours, ensuring your engineering cycles keep pace with rapid design changes.
You can perform various analyses including structural, thermal, and fluid dynamics within a single interface. The platform is particularly effective for mid-to-large scale manufacturing companies in the automotive, aerospace, and electronics sectors. By capturing and automating repetitive modeling tasks, you reduce human error and free up your engineering team to focus on interpreting results and optimizing product performance.
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.
