Definitions
| Field | Content | SI Unit Example |
|---|---|---|
| Tstart | (Optional) Start time
for kinetic energy relaxation. Default = 0.0 |
|
| Tstop | (Optional) Stop time
for kinetic energy relaxation. Default = Final time of the analysis |
Comments
- Set all velocities to
0 each time the kinetic energy reaches a maximum.
Figure 1. - It is not advised to use /KEREL with combined Advanced mass Scaling and Single Precision.
- If the maximum kinetic energy is reached due to the elastic vibration of shell or solid part, the result can be wrong because the stress, strain and strain rate tensors in the element will no longer be in equilibrium.
