createMortarInterface()

void MortarInterfaceWarehouse::createMortarInterface	(	const std::pair< BoundaryID, BoundaryID > &	boundary_key,
		const std::pair< SubdomainID, SubdomainID > &	subdomain_key,
		SubProblem &	subproblem,

		const bool	debug,
		const bool	correct_edge_dropping,
		const Real	minimum_projection_angle,
		const MooseEnum &	triangulation,
		const bool	triangulate_triangles
	)

Create mortar generation object.

Parameters

boundary_key	The primary-secondary boundary pair on which the AMG objects lives
subdomain_key	The primary-secondary subdomain pair on which the AMG objects lives
subproblem	A reference to the subproblem
on_displaced	Whether the AMG object lives on the displaced mesh
periodic	Whether the AMG object will be used for enforcing periodic constraints. Note that this changes the direction of the projection normals so one AMG object cannot be used to enforce both periodic and non-periodic constraints
debug	whether to output mortar segment mesh exodus file for debugging purposes
correct_edge_dropping	edge dropping treatment selection
minimum_projection_angle	minimum projection angle allowed for building mortar segment mesh
triangulation	triangulation strategy used for clipped 3D mortar polygons
triangulate_triangles	whether a clipped polygon that is already a triangle should still be subdivided
