 \section overview Overview
 
-The IntersectionDEC enables the conservative remapping of fields between two parallel codes. This remapping is based on the computation of intersection volumes between elements from code A and elements from code B. The computation is possible for 3D meshes, 2D meshes, and 3D-surface meshes. Dimensions must be similar for code A and code B (for instance, though it could be desirable, it is not yet possible to couple 3D surfaces to 2D surfaces).

 A typical use of IntersectionDEC encompasses two distinct phases :
 - A setup phase during which the intersection volumes are computed and the communication structures are setup. This corresponds to calling the IntersectionDEC::synchronize() method.

-Computing the field on the receiving side can be expressed in terms of a matrix-vector product : \f$ \phi_t=W.\phi_s\f$, with \f$ \phi_t \f$ the field on the target side and \f$ \phi_s \f$ the field on the source side.

-\section surface Special features for 3D surface remapping
-When remapping a 3D surface to another 3D surface, a projection phase is necessary to match elements from both sides. Care must be taken when defining this projection to avoid non conservative remappings.

+ A \ref conservativeremapping of the field from the source mesh to the target mesh is performed by the function synchronise(), which computes the \ref remappingmatrix .
