Overview
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.
SkyCiv
SkyCiv is a cloud-based structural analysis and design platform that lets you work from any device without installing heavy desktop software. You can model, analyze, and design structures ranging from simple beams to complex 3D frames and trusses directly in your web browser. The platform integrates seamlessly with international design codes, allowing you to perform checks for steel, concrete, wood, and cold-formed sections with automated report generation.
By moving your engineering workflow to the cloud, you can collaborate with your team in real-time and access your projects from anywhere. It solves the problem of expensive hardware requirements and rigid licensing, making it a flexible choice for solo engineers and large firms alike. You can also automate repetitive modeling tasks using their powerful API, significantly cutting down your project turnaround time.
