Figure 11

Boundary layer mesh of a rat lung. Panel A shows the feature size fields on the lung surface, as well as the locations of the cutaway sections in panels B–E. Panel B shows the boundary prism and interior tetrahedra at a region where a large airway transitioning to a smaller airway. Panels C and D show the sections through the trachea and through a pair of airways downstream of the bifurcation, respectively. Panel E shows the resulting surface mesh in the neighborhood of several outlets, where the faces are constrained (see subsection 5.3)
