Figure 114. LS-DYNA diagnostics for the stable time step. Instructions.

Control contact.

The LS-DYNA time step size should not exceed 0.235E-02 to avoid contact instabilities. If the step size is (words missing?) bigger then scale the penalty of the offending surface. This LS-DYNA output diagnostic lists the increment number, time, time step, and action (write plot file or flush buffers). The list starts with increment 0 at time 0 and ends with increment 23649 at time 50.002. The time step is 2.11E-03 for all times. The time step does not exceed the stable value of 2.35E-03.

Control timestep.

If the step size is (words missing?) bigger then scale the penalty of the offending surface.This LS-DYNA output diagnostic lists the increment number, time, time step, and action (write plot file or flush buffers). The list starts with increment 0 at time 0 and ends with increment 31210 at time 50.001. The time step ranges between 2.23E-03 and 1.37E-03. These time steps do not exceed the stable value of 2.35E-03.
