Explicit Dynamics -

Will your smartphone survive a 1.5m drop onto concrete? Explicit dynamics models the micro-second of impact, the propagation of the shockwave through the glass, and the resulting fracture.

That tiny step isn't a bug; it's the physics. You are literally simulating the propagation of a stress wave across your model. For a steel beam being hit by a projectile, that wave moves fast. To capture it, you must move faster. explicit dynamics
