Gap
range for bonding |
Specifies the clearance that
allows geometric entities to qualify for bonding interactions. The
default value for Maximum gap
percent is 0.01 %
of the characteristic length of the model and is specified in
. Components that have clearances larger than this
threshold are not bonded at a component-level. You can overwrite the
default maximum clearance with a user-defined value. Enter a very small value rather than zero for
maximum clearance to ensure bonding of curved, coincident
geometry.

Calculate minimum gap |
This tool is available when you
select two components in Components for
interaction to apply a bonded contact. Calculates the minimum distance between the two
selected components.
|
Include shell edge-solid face/shell face and edge pairs
(slower) |
Creates edge-to-edge bonded
contact sets for pairs of edges located within the allowable
clearance for bonding.The valid pairs of edges of
shells or sheet metal bodies that qualify for bonding are:
- Straight, parallel, and non-interfering
shell edges (or almost parallel within one degree of
tolerance).
- Circular edges that have the same
radius, are concentric, and do not interfere.
- Shell edges (straight or arc) bonded to
a solid or shell face (planar or cylindrical).

Gap range to
consider contact: |
Specifies the clearance that
allows geometric entities to qualify for contact. The default value
specified in is 10 % of the
characteristic length of the model. |
Stabilize the area
if the gap is: |
Applies a small stiffness to the
qualified areas so the solver can overcome instability issues and
start the simulation. The software applies contact stabilization to
components that have an initial clearance within a threshold value
of 1% of the model's characteristic length. You
can customize the allowable clearances to better fit your
models.
|
Coefficient of friction |
Specifies the coefficient of
static friction for the selected component. The allowable range for
the friction coefficient is 0 to 1.0. The static
friction forces are calculated by multiplying the normal forces
generated at the locations that come into contact by the given
coefficient of friction. The direction of the friction force is
opposite to the direction of motion.
