What is Explicit Dynamics?

Many transient dynamic simulations require extremely small integration time steps, for examples, high speed impact, drop test, or highly nonlinear problems. In such cases, the time steps may be as small as several nanoseconds, and the use of transient structural analysis system becomes impractical, since the run time would be too enormous to be accepted. The integration method used in the transient structural analysis

Problem Statement:
