SBMInterfaceManager

SBMInterfaceManager detects shared interfaces in one saved surface mesh containing the complete boundary of each subdomain. It groups surface elements by subdomain ID, matches coincident faces with the same vertices between each pair, and builds a k-d tree for distance and normal queries on each detected interface. The interface meshes must therefore be conformal; partial face overlaps are not treated as complete interface elements.

The source mesh must be replicated, have dimension one less than the solving mesh, and use subdomain IDs that identify the enclosed regions. Each per-subdomain surface must use outward-facing element normals. A query for (first, second) returns the normal from the first subdomain toward the second; reversing the pair reverses that normal.

Set complete_interface_mesh to a mesh retained by a MeshGenerator with save_with_name. The tolerance parameter is relative to the largest dimension of the complete surface mesh and controls coincident-face matching. normal_tolerance controls the parallel-normal check.

The manager can be queried directly by UnsignedDistanceToSurfaceMesh, or used by the shifted cohesive zone action through its complete_interface_mesh parameter.

Detects shared interfaces between subdomains in a single surface mesh that contains the complete boundary of each subdomain, and provides distance and normal queries for each interface.
