Specifies termination criteria for an explicit dynamic analysis.
Option
Label identifying the option to be performed.
ADD | — | Define termination criteria (default). |
DELE | — | Delete termination criteria. |
LIST | — | List termination criteria. |
Lab
Label identifying the type of termination (no default).
NODE | — | Terminate solution based on nodal point coordinates.
The analysis terminates when the current position of the specified node reaches
either the maximum or minimum coordinate value ( |
PART | — | Terminate solution based on rigid body (part)
displacements. The analysis terminates when the displacement of the center
of mass of the specified rigid body reaches either the maximum or minimum
value ( |
NUM
Node number (if Lab
= NODE) or
rigid body Part ID (if Lab
= PART). (No default.)
STOP
Criterion for stopping the solution (no default).
1 | — | Global X-direction. |
2 | — | Global Y-direction. |
3 | — | Global Z-direction. |
4 | — | For |
MAXC
Maximum (most positive) coordinate value (Lab
=
NODE) or displacement (Lab
= PART). MAXC
defaults
to 1.0e21
MINC
Minimum (most negative) coordinate value (Lab
=
NODE) or displacement (Lab
= PART). MINC
defaults
to -1.0e21.
No termination criteria are defined other than the termination time set on the TIME command.
You may specify multiple termination criteria using EDTERM; the solution will terminate when any one of the criteria is satisfied, or when the solution end time (specified on the TIME command) is reached.
In an explicit dynamic small restart analysis (EDSTART,2)
or full restart analysis (EDSTART,3), the termination criteria
set in the previous analysis (the original analysis or the previous restart)
are carried over to the restart. If the previous analysis terminated due to
one of these criteria, that specific criterion must be modified so that it
will not cause the restart to terminate prematurely. In particular, if a termination
condition based on nodal contact (Lab
= NODE, STOP
=
4) is satisfied, this condition must be deleted and replaced with a condition
based on nodal coordinates for that same node. (If a condition based on nodal
coordinates already exists for that node, the replacement is not necessary.)
In the restart, the number of termination criteria specified using EDTERM cannot
exceed a maximum of 10 or the number specified in the original analysis.
Note that the termination criteria set by EDTERM are not active during dynamic relaxation (EDDRELAX).
This command is also valid in PREP7.
