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.
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.
