- ADJUST
-
Set ADJUST=YES (default) to resolve clearances by adjusting the nodal coordinates without creating strain in the model. ADJUST=YES can be used only for clearances defined in the first step of an analysis.
Set ADJUST=NO to store contact offsets so that the clearances can be satisfied without adjusting the nodal coordinates.
- CLEARANCE
-
Set this parameter equal to the value of the initial clearance for the entire set of slave nodes or to the name of a nodal distribution (see Distribution definition). The clearance values must be non-negative for slave nodes on solid element surfaces. The default value is 0.0.
- SEARCH ABOVE
-
Set this parameter equal to the distance above the surfaces that will be searched for slave nodes to be included in the clearance specification. The default for solid elements is approximately one-tenth of the element size of the elements attached to a slave node. The default for structural elements (e.g., shell elements) is the thickness associated with the slave node.
This parameter cannot be used if the SEARCH NSET parameter has been used.
- SEARCH BELOW
-
Set this parameter equal to the distance below the surfaces that will be searched for slave nodes to be included in the clearance specification. The default for solid elements is approximately one-tenth of the element size of the elements attached to a slave node. The default for structural elements (e.g., shell elements) is the thickness associated with the slave node.
This parameter cannot be used if the SEARCH NSET parameter has been used.
- SEARCH NSET
-
Set this parameter equal to the name of the node set containing the slave nodes to be included in the clearance specification. The specified clearance will be enforced at all slave nodes in this node set irrespective of whether they are above or below their respective master surfaces. This parameter can also be used to identify initially bonded nodes in a VCCT analysis.
This parameter cannot be used if either the SEARCH ABOVE or SEARCH BELOW parameter has been used.
