/IMPL/SINIT
Engine Keyword Describes the initial stresses that will be imposed gradually.
Format
/IMPL/SINIT
Comments
- This keyword is used only for
nonlinear implicit analysis and it is recommended to use when there is out-of
balance at initial state due to initial stresses.
Example: in /IMPL/SPRBACK, initial stresses will be added gradually (proportional to the time passed) to avoid high out-of-balance forces during each increment so that the convergence is better managed. When there is loading in the analysis, linear function (of time) is recommended for loading, if possible.
- When monitored volume type 3 is available in the model, the keyword is activated automatically.
