WebJul 19, 2010 · Element deletion is crucial if you simulate parts that can fly away (e.g. during a crash), or penetration occurs, but there are some issues. Deleting the element removes mass and energy of the system. The mass and energy of the system is shared on the nodes, and the ones which become free after the element deletion, simply fly away.
