The use of the Med Memory libraries may -make easier the code coupling in the Salome framework. With these classes, it -is possible to: - -- read/write meshes and fields from MED-files; -- create fields containing scalar or vectorial values on list of elements -of the mesh; -- communicate these fields between different components; -- read/write such fields. - -Note that on the figure \ref fig_UML_light as well as on figure -\ref fig_UML the life cycle of mesh and field objects are independent. Destroying a field will have no effect on the mesh. But the user has to maintain the link: a mesh aggregates a support which aggregates a field. If the user has to delete Med Memory objects, the field has to be deleted first, then the support and finally the mesh. - -A more advanced usage of the Med Memory is possible through other classes. -Figure \ref fig_UML gives a complete view of the Med Memory API. It includes : - -- \b GROUP a class inherited from the SUPPORT class used to create supports linked to mesh groups. It stores restricted list of elements used to set boundary conditions, initial values. -- \b FAMILY which is used to manipulate a certain kind of support which does not intersect each other. -- \b MESHING which builds meshes from scratch, it can be used to transform meshes from a specific format to the MED format or to integrate a mesher within Salome platform (note that class does not add element or node to a mesh). -- \b GRID which enables the user to manipulate specific functions for structured grid. - -\anchor fig_UML -\image html UML_small.png "UML diagram of Med Memory API classes" -\image latex UML_small.eps "UML diagram of Med Memory API classes" - - -\subsection medmem_enums Enums -A few enums are defined in the \c MED_EN namespace : - -- an enum which describes the way node coordinates or field values are stored, - - \c MED_FULL_INTERLACE for arrays such that \f$ x_1,y_1,z_1,x_2,y_2,z_2,\ldots,x_n,y_n,z_n \f$; - - \c MED_NO_INTERLACE for arrays such that \f$ x_1,x_2,\ldots,x_n,y_1,y_2,\ldots,y_n,z_1,z_2,\ldots,z_n \f$; - - \c MED_UNDEFINED_INTERLACE, the undefined interlacing mode. - . -- an enum which describes the type of connectivity - - \c MED_NODAL for nodal connectivity; - - \c MED_DESCENDING for descending connectivity. - . - -The user has to be aware of the fact that the Med Memory considers only meshes defined by their nodal connectivity. Nevertheless, the user may, after loading a file in memory, ask to the mesh object to calculate the descending connectivity. - -- an enum which contains the different mesh entities, \c medEntityMesh, the entries of which being : - - \c MED_CELL - - \c MED_FACE - - \c MED_EDGE - - \c MED_NODE - - \c MED_ALL_ENTITIES - . - -In 3D (resp. 2D), the user has to be aware of the fact that only mesh -entities \c MED_CELL and \c MED_FACE (resp. \c MED_EDGE) are -considered.
