WORC vs SimScale
Both run in the browser and have free tiers. The difference: WORC is unlimited and free, with your FEA wired to your calculations and docs; SimScale is cloud-based CAE with deeper, broader multiphysics including CFD.
Where each fits
SimScale is a strong, established platform — if you need cloud horsepower or advanced multiphysics like CFD and electromagnetics, that's where it shines, and WORC doesn't try to match that breadth. WORC is for fast structural, thermal, and modal analysis in the browser — unlimited and free, your work stays private so you can use it on real, commercial projects, and connected to the calculations and report around it.
The key differences
- Free, and unlimited — WORC: free, with no simulation caps. SimScale: a free Community plan, but capped at 10 simulations and 3,000 core-hours.
- Physics — WORC: structural, thermal, modal. SimScale: broader multiphysics including CFD and electromagnetics.
- Private & commercial-friendly — WORC: your work stays private, so you can use it on real, commercial projects. SimScale: every Community-plan project is public.
- Connected to the rest of your work — WORC: FEA wired to your calculations, code, and docs. SimScale: focused on simulation.
Run FEA without the cloud queue
WORC is free to use, runs in your browser, and needs no install or login to start. You only pay when you want the AI assistant, accelerated compute, or enterprise features.
