Required parameters

TYPE

Set TYPE=QUASI-NEWTON to specify a quasi-Newton solution method.

Set TYPE=SEPARATED to specify that linearized equations for the individual fields in a fully coupled procedure are to be decoupled and solved separately for each field. This option can be specified only with the COUPLED THERMAL-ELECTRICAL procedure and the COUPLED TEMPERATURE-DISPLACEMENT procedure without the ELECTRICAL parameter.

Set TYPE=LCP CONTACT to activate the linearized contact capability to solve for contact status and contact stresses. This option can be specified only within a static perturbation step with small sliding, frictionless contact.

Optional parameters

REFORM KERNEL: This parameter can be used only with TYPE=QUASI-NEWTON. Set this parameter equal to the number of quasi-Newton iterations allowed before the kernel matrix is reformed. The default is REFORM KERNEL=8.

Data line for TYPE=LCP CONTACT

First (and only) line

Initial gap distance to specify a zone within which potential contact constraints are exposed to the LCP solver. In the case of multiple contact pairs, this global setting applies to all of them. By default, a gap distance is calculated internally for each contact pair based on a characteristic facet size associated with the contact pair.
Scale factor for the initial gap distance specified in the previous entry or the internally computed (contact) pair-wise gap distances. The default is 1.0.
