Comments
- Can be used only if Starter Input uses Block Format.
- It is not advised to use /KEREL/1 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.
