- subdomainThe subdomain that the variable lives on
C++ Type:SubdomainName
Controllable:No
Description:The subdomain that the variable lives on
- variableThe name of the variable to test for contact
C++ Type:VariableName
Controllable:No
Description:The name of the variable to test for contact
ContactDOFSetSize
The ContactDOFSetSize class outputs the number of degrees of freedom greater than a certain tolerance (specified through the tolerance parameter; the default value is 1e-6). The usual application of this, as indicated by the class name, is to indicate how many nodes (if using first order Lagrange shape functions for the contact pressure lagrange multiplier) or element faces (if using constant monomials) are in contact. The subdomain parameter should be the name or id representing the lower dimensional block that the Lagrange multiplier variable lives on.
Description and Syntax
Outputs the number of dofs greater than a tolerance threshold indicating mechanical contact
