CRPLIM, CRCR, Option
Specifies the creep criterion for automatic time stepping.
CRCRValue of creep criteria for the creep limit ratio control.
OptionType of creep analysis for which the creep limit ratio is specified:
1 (or ON) | — | Implicit creep analysis. |
0 (or OFF) | — | Explicit creep analysis. |
For implicit creep (Option = 1), CRCR defaults to zero (i.e., no creep limit control).
For explicit creep (Option = 0), CRCR defaults to 0.1
The CUTCONTROL command can also be used to set the creep criterion and is preferred over this command for setting automatic time step controls.
The creep ratio control can be used at
the same time for implicit creep and explicit creep analyses. For
implicit creep (Option = 1), the default
value of CRCR is zero (i.e., no creep limit
control), and you can specify any value. For explicit creep (Option = 0), the default value of CRCR is 0.1, and the maximum value allowed is 0.25.
This command is also valid in PREP7.
