Gap
range for bonding: |
Specifies the maximum clearance that allows geometric
entities to qualify for bonding interactions. The default value is
0.01 % of the characteristic
length of the model.
Geometric
entities that have clearances larger than this threshold are not
bonded on a
global-level. |
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 maximum clearance that allows geometric
entities
to
qualify for contact.
The default value 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
geometries that have an initial clearance within a threshold value
of 1% of the model's characteristic length. |
Coefficient of
friction |
Specifies the coefficient of static friction for global
contact conditions. 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.
For local contact conditions,
you specify a friction coefficient in the Local Interactions
PropertyManager.
