Detailed Description

Side volume element for skeleton integration.

This header defines VolumeElementForcesAndSourcesCoreOnSide, which extends VolumeElementForcesAndSourcesCore to evaluate volume finite elements on a selected face (the "skeleton"). It provides connectivity maps, face orientation information, and access to face geometry (normals, tangents) for implementing mortar methods, flux terms, and interface conditions.

The nested UserDataOperator adapts the standard volume operator interface for side evaluations. Users inherit from UserDataOperator and override methods like doWork() to assemble residuals and tangent contributions using face normals at Gauss points, face coordinates, and the skeleton sense.

Typical usage:

1. Instantiate VolumeElementForcesAndSourcesCoreOnSide for each side
2. Attach a derived UserDataOperator to handle side-specific assembly
3. Loop over face elements on the skeleton
4. For each face, find adjacent volume elements (sides) and loop over both
5. Access getFaceSideNumber(), getSkeletonSense(), getNormal(), etc. in your operator to retrieve face geometry and orientation for each side
