autots

Mapdl.autots(key='', **kwargs)

Specifies whether to use automatic time stepping or load stepping.

APDL Command: AUTOTS

Parameters
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).

Notes

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.
