Function Documentation

communicateGaps()

void Moose::Mortar::Contact::communicateGaps	(	std::unordered_map< const DofObject *, std::pair< ADReal, Real > > &	dof_to_weighted_gap,
		const MooseMesh &	mesh,
		bool	nodal,
		bool	normalize_c,
		const Parallel::Communicator &	communicator,
		bool	send_data_back
	)

This function is used to communicate gaps across processes.

Parameters

dof_to_weighted_gap	Map from degree of freedom to weighted (weak) gap
mesh	Mesh used to locate nodes or elements
nodal	Whether the element has Lagrange interpolation
normalize_c	Whether to normalize with size the c coefficient in contact constraint
communicator	Process communicator
send_data_back	After aggregating data on the owning process, whether to send the aggregate back to senders. This can be necessary for things like penalty contact in which the constraint is not enforced by the owner but in a weighted way by the displacement constraints
