Overview
COMSOL Multiphysics
COMSOL Multiphysics gives you a unified environment to simulate designs, devices, and processes across diverse engineering and scientific fields. You can model coupled or multiphysics phenomena by combining any number of physics interfaces into a single model. This flexibility allows you to move beyond single-physics limitations and capture the real-world behavior of your products more accurately.
You can build your own simulation apps using the Application Builder and distribute them to colleagues or clients via COMSOL Compiler or COMSOL Server. This democratizes simulation, allowing team members without modeling expertise to run their own tests. Whether you are working in electromagnetics, structural mechanics, acoustics, or fluid flow, you can manage the entire modeling workflow from geometry creation to physics setup and results visualization within one interface.
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.
