OPNCONTROL, Lab, VALUE, NUMSTEP
Sets decision parameter for automatically increasing the time step interval.
MP ME ST PR PRN <> <> <> EM <> <> PP <>
DOF | — | DOF label used to base a decision for increasing the time step (substep) interval in a nonlinear or transient analysis. The only DOF label currently supported is TEMP. |
OPENUPFACTOR | — | Factor for increasing the time step interval. Use Lab = OPENUPFACTOR (when AUTOTS,ON is invoked) and specify a VALUE greater than 1.0. Default for OPENUPFACTOR is 1.5. The upper limit for OPENUPFACTOR is 10.0. However, we recommend using a value not greater than 3.0. |
Two values used in algorithm for deciding if the time step interval can be increased. The time step interval is increased if the maximum absolute value of the incremental solution at the specified DOF label is less than VALUE for the number of contiguous time steps specified by NUMSTEP. The default for VALUE is 0.1 and the default for NUMSTEP is 3. NUMSTEP is used only when Lab = DOF.
This command is available only for nonlinear or transient analysis, and only when SOLCONTROL,ON.
