71e94accymsim: nonlinear FEM cymbal simulation packageJeremy Magland 1# Soft mallet, gong-like stroke on an 18 inch medium-thin crash (the prototype's default run).
2# The mallet injects only low frequencies; everything above a few hundred Hz comes from the
3# nonlinear cascade. Units are SI throughout (m, kg, s, Pa). See docs/model.md.
