Visual simulators are the most concept-focused part of the simulation library. They emphasize diagrams, motion, fields and direct manipulation so that relationships such as resonance, superposition, induction, refraction, cavitation or crack growth can be understood visually before moving to more detailed calculations.
Choose a tool below by purpose. Individual pages include their own assumptions, equations, references and limitations where applicable.
