3D Connexion Version 6.6

*RESTART

If this parameter is omitted, the restart will begin at the end of the stepspeciﬁed on the STEP

parameter.

ITERATION

If the new analysisis restarted from a previous direct cyclic analysis, set this parameter equal to the

iteration number within the speciﬁedstep of the direct cyclic analysis after which the analysis will

resume. Since the new analysis can be restarted only from the end of a loading cycle in the previous

direct cyclic analysis, the INC parameter is irrelevant andis ignored if the ITERATION parameter

is speciﬁed.

If this parameter is omitted, the restart will begin at the end of the last iteration for the speci ﬁed

step.

STEP

Set this parameter equal to the step number at which the restart will be made.

If this parameter is omitted, the analysis will restart a t the last available step found.

Optional parameters if the WRITE parameter is used:

FREQUENCY

This parameter speciﬁes the increments at which restart informationwill be written. Forexample,

FREQUENCY=2will write restart information at increments 2, 4, 6, etc. Fora direct cyclic analysis

this parameter speciﬁes the iteration numbers at which re start information will be written; restart

information will be written onlyat the end of an iteration. Whenrestart is requested in an analysis,

restart information is always written at the end of a step. Set FREQUENCY=0 to discontinue the

writing of restart data.

The FREQUENCY and NUMBER INTERVAL parameters are mutually exclusive. The

default is FREQUENCY=1.

NUMBER INTERVAL

Set this parameter equal to the number of intervals during the step at which the *RESTART data

are to be written. The value of this parameter must be a positive integer.

The FREQUENCY and NUMBER INTERVAL parameters are mutually exclusive. The

default is FREQUENCY=1.

TIME MARKS

Set TIME MARKS=YES (default) to write results at the exact times dictated by the NUMBER

INTERVAL parameter.

Set TIME MARKS=NO to writethe restart at the increment ending immediately after the time

dictated by the NUMBER INTERVAL parameter.

OVERLAY

This parameter speciﬁes that only one increment should be retainedper step, thus minimizing the

storage space needed.
