To solve this simulation to a 2011 ANSYS, Inc. The resulting stability time step would be 0.18 -seconds. The time steps used for explicit time integration will generally be much smaller than those used for implicit time integration characteristic dimension of 1 mm and a material sound speed of 5000 m/s. This condition implies that the time step be limited such that a disturbance (stress wave) cannot travel further than the smallest characteristic element dimension in the mesh, in a single time step. Stability Time StepTo ensure stability and accuracy of the solution, the size of the time step used in Explicit time integration is limited by the CFL (Courant-Friedrichs-Levy) condition.
