pack_gap

Computes distance vector from surface with index origin_meshtag to other surface Requires create_distance_map to be called beforehand.

Input

• origin_meshtag - index of surface on which to integrate

Output

• {c, cstride}: gap packed on facets. c[icstride + gdimk +j] contains jth component of the gap on the ith facet at kth quadrature point

Member variables accessed

• _qp_phys
• _facet_maps (created with create_distance_map)
• _facets
• _qp_ref_facet (shape only)

Changes needed for variable gap

• _qp_phys must be computed on submesh with updated geometry
• master_coords has to be computed on submesh with updated geometry
