zone interface tolerance-contact command

Syntax

zone interface <s > tolerance-contact f keyword <range>

Primary keywords:

add    gradient    multiply    vary

Sets the maximum depth of penetration (of faces that contact an interface) for which a contact is detected. If this depth (or overlap) is greater than value, then no contact is detected. By default, the value is determined from zone dimensions and is updated if deformation occurs during a simulation.

The parameter may be used to force contact detection if a large initial overlap exists between two bodies. Use with caution, because large geometrical overlaps maybe physically unrealistic. The current values of contact-tolerance can be displayed with zone.interface s list information. If the interface name is not given then the command operates on all interfaces.

If an interface name s is given the command is applied only to nodes of that interface, otherwise the command is applied to nodes in all interfaces in the optional range.

add

Add the specified value to the existing value.

gradient v <origin v >

Apply a gradient to the scalar-value provided. Note the origin keyword is optional, however, the default value (0,0,0) is used if the origin keyword is not included in the command — which may not produce the intended result.

multiply

Multiply the existing value by the specified value.

vary v

Apply a linear variation to the scalar-value provided.
