ComputeWeightedGapCartesianLMMechanicalContact
The Karush-Kuhn-Tucker conditions of mechanical contact are:
where is the gap and is the contact pressure, a Lagrange multipler variable living on the secondary face. Per (Wohlmuth, 2011) and (Popp and Wall, 2014), the variationally consistent, discretized version of the KKT conditions are:
where indicates the normal direction, denotes the j'th secondary contact interface node, and is the discrete weighted gap, computed by:
where denotes the secondary contact interface, is the j'th lagrange multiplier test function, and is the discretized version of the gap function.
The KKT conditions are enforced using a nonlinear complimentarity problem (NCP) function, in this case the most simple such function, , where (implemented with the input parameter c) is used to balance the size of the gap and the normal contact pressure. If the contact pressure is of order 10000, and the gap is of order .01, then c should be set to 1e6 in order to bring components of the NCP function onto the same level and achieve optimal convergence in the non-linear solve.
The ComputeWeightedGapCartesianLMMechanicalContact object computes the weighted gap and applies the KKT conditions using Lagrange multipliers defined in a global Cartesian reference frame. As a consequence, the number of contact constraints at each node will be two, in two-dimensional problems, and three, in three-dimensional problems. The normal contact pressure is obtained by projecting the Lagrange multiplier vector along the normal vector computed from the mortar generation objects. The result is a normal contact constraint, which, in general, will be a function of all (two or three) Cartesian Lagrange multipliers. This methodology only constrains one degree of freedom. The other degree(s) of freedom are constrained by enforcing that tangential tractions are identically zero. Note that, if friction with Cartesian Lagrange multipliers is chosen via ComputeFrictionalForceCartesianLMMechanicalContact, those remaining nodal degrees of freedom are constraint using Coulomb constraints within a semi-smooth Newton approach. Usage of Cartesian Lagrange multipliers is recommended when condensing Lagrange multipliers via the variable condensation preconditioner (VCP) VariableCondensationPreconditioner.
The user can also employ locally oriented Lagrange multipliers ComputeWeightedGapLMMechanicalContact, which minimizes the number of contact constraints for frictionless problems.
Computes the weighted gap that will later be used to enforce the zero-penetration mechanical contact conditions

- ghost_higher_d_neighborsFalseWhether we should ghost higher-dimensional neighbors. This is necessary when we are doing second order mortar with finite volume primal variables, because in order for the method to be second order we must use cell gradients, which couples in the neighbor cells.
Default:False

- minimum_projection_angle40Parameter to control which angle (in degrees) is admissible for the creation of mortar segments.
