Particles In A Solid

The Ejs Standing Waves in a Pipe model displays the displacement and pressure waves for a standing wave in a pipe. The pipe can be closed on both ends, on one end, or open on both ends. The number of nodes in the standing waves can be changed via a slider. You can modify this simulation if you...

Hubble in a bottle! is a scientific visualization tool for TIPSY files with plenty of optimizations (3dnow for AMD and SSE for Intel processors) and the ability to run on large supercomputer clusters using the MPI library. The model can be rotated intuitively using quaternions and in real time...

The STP Sensitivity to Initial Conditions program shows 11 particles in a line with the same velocity. You can perturb the system slightly and observe how sensitive the trajectory is to a small change. The default perturbation strength is 1.00001. STP SensitivityToInitialConditions is part of a...
