| Ignore |
Flag to ignore
secondary nodes if no main segment found. 13
14
- =0
- Set to 1000.
- =1
- Secondary nodes with no main segment found during
the Starter are deleted from the interface.
- =2
- Secondary nodes with no main segment found during
the Starter are deleted from the interface, new
calculation for
dsearch,
if
dsearch=
0.
- =3
- Secondary nodes with no main segment found during
the Starter are deleted from the interface, new
calculation for
dsearch,
if
dsearch=
0.
- =1000 (Default)
- No deletion of secondary nodes.

Spotweld formulation
flag. 4

12
- =0
- Set to 4, if /CAA is
used.
- Set to 5, if
/CAA is not used.
- =1
- Formulation is optimized for spot welds or
rivets.
- =2
- Same formulation as standard formulation. Required
when using hierarchy levels. Not compatible with
nodal time step,
/DT/NODA/CST.
- =4 Default, if
/CAA is used.
- Rotational DOF are not transmitted, if shells are
used. Not compatible with nodal time step
/DT/NODA/CST.
- =5 Default, if
/CAA is not used.
- Standard formulation.
- = 20, 21,
22
- Formulation with failure. Not compatible with nodal
time step, /DT/NODA/CST. The
stress is computed for each secondary node according
to the "equivalent" surface around the node. The
equivalent surface is defined accordingly:
- =20
- Surface computed using shell and brick faces
attached to the node.
- =21
- Surface computed using only the shell attached
to the node.
- =22
- Surface computed using only the brick faces
attached to the node.
- =25
- Penalty formulation (not recommended). 19
- =27
- Kinematic formulation similar to Spotflag =5 with an automatic switch to penalty
formulation when incompatible kinematic conditions
occur. 20
- =28
- Kinematic formulation similar to Spotflag =1 with an automatic switch to penalty
formulation when incompatible kinematic conditions
occur. 20
- =30
- Formulation with cubic curvature of main segment.
Not compatible with nodal time step,
/DT/NODA/CST.

| Isearch |
Search formulation
flag for the closest main segment.
- =0
- Set to 2.
- =1
- Old formulation (only used for previous
version).
- =2 (Default)
- New improved formulation.
(Integer) |

| Idel2 |
Node deletion flag.

16
- =0
- Set to 1000.
- =1
- Kinematic condition is suppressed on the secondary
node, when all elements linked to the main segment
are deleted. (The secondary node is removed from the
interface).
- =2
- Kinematic condition is suppressed on the secondary
node, if the main element is deleted. (The secondary
node is removed from the interface).
- =1000 (Default)
- No deletion.

| Istf |
Interface stiffness
definition flag. 17
Only used with penalty formulations ( Spotflag= 25, 27 or
28)
- =0
- Set to 2.
- =1
- Penalty stiffness is the main stiffness.
- =2 (Default)
- Penalty stiffness is the average of the main and
secondary stiffness.
- =3
- Penalty stiffness is the maximum of the main and
secondary stiffness.
- =4
- Penalty stiffness is the minimum of the main and
secondary stiffness.
- =5
- Penalty stiffness is the main and secondary
stiffness in series.
