opensg.compute_utils.dof_mapping_quad(V, v2a, V_l, w_ll, boundary_facets_left, entity_mapl)

dof mapping makes solved unknown value w_l(Function(V_l)) assigned to v2a (Function(V)). The boundary of wind blade mesh is a 1D curve. The facet/edge number is obtained from cell to edge connectivity (conn3) showed in subdomain subroutine. The same facet/edge number of extracted mesh_l (submesh) is obtaine din entity_mapl (gloabl mesh number). refer how submesh was generated. Therefore, once identifying the edge number being same for global(mesh)&boundary mesh(mesh_l), we equate the dofs and store w_l to v2a. The dofs can be verified by comparing the coordinates of local and global dofs if required.

Parameters:

• V (_type_) – _description_

• v2a (_type_) – _description_

• V_l (_type_) – _description_

• w_ll (1D array (len(4))) – Fluctuating function data for case p

• boundary_facets_left (_type_) – _description_

• entity_mapl (_type_) – _description_

Returns:

_type_ – _description_
