ComputeWeightedGapLMMechanicalContact
The Karush-Kuhn-Tucker conditions of mechanical contact are:
where is the gap and is the contact pressure, a Lagrange multiplier 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 ComputeWeightedGapLMMechanicalContact object computes the weighted gap and applies the KKT conditions. The KKT conditions are enforced using a nonlinear complementarity 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.
Computes the weighted gap that will later be used to enforce the zero-penetration mechanical contact conditions

Default:False
C++ Type:bool
Controllable:No
Description:Whether we should ghost point neighbors of secondary face elements, and consequently also their mortar interface couples.
- interpolate_normalsFalseWhether to interpolate the nodal normals (e.g. classic idea of evaluating field at quadrature points). If this is set to false, then non-interpolated nodal normals will be used, and then the _normals member should be indexed with _i instead of _qp

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

This parameter is mostly intended for mortar mesh debugging purposes in two dimensions.
