Simulation
Tools that model and simulate physical, mechanical, electrical and visual phenomena in the browser, from finite element analysis and circuit behavior to fluids, mechanisms and materials data. They allow testing an idea or understanding a principle before building anything.
Engineers can use finite element analysis tools, circuit simulators, microcontroller simulators and fluid or particle simulators. Planar mechanism simulators, gear and heat sink design tools, beam and buckling calculators and G-code simulators cover mechanical design. Chemical equilibrium solvers, orbital and sun position simulators, materials property databases and interactive physics simulations complete the selection.
