Adaptive solver: re-mesh strategy in 3D

Mesh selecting and cutting process

Assuming that the physical phenomena are often located near the interface between regions, the adaptive solver focuses on the volume elements close to the interface. The volume elements corresponding to the most important errors are selected to deduce the face elements which will be refined. The technique of refinement is applied on the 2D mesh. Then, the final 3D mesh is built from to the refined 2D mesh.
