AUTOTS, Key
Specifies whether to use automatic time stepping or load
stepping.
Key
Automatic time stepping key:
OFF | — | Do not use automatic time stepping. |
ON | — | Use automatic time stepping (default). |
AUTO | — | The program determines whether to use automatic time stepping (used by Workbench). |
Specifies whether to use automatic time stepping (or load stepping)
over this load step. If Key
= ON, both
time step prediction and time step bisection will be used.
You cannot use automatic time stepping [AUTOTS], line search [LNSRCH], or the DOF solution predictor [PRED] with the arc-length method [ARCLEN, ARCTRM]. If you activate the arc-length method after you set AUTOTS, LNSRCH, or PRED, a warning message appears. If you choose to proceed with the arc-length method, the program disables your automatic time stepping, line search, and DOF predictor settings, and the time step size is controlled by the arc-length method internally.
This command is also valid in PREP7.
