36 * \anchor ParaMESH-det
38 * Parallel representation of an unstructured mesh.
40 * This class is very specific to the requirement of parallel code computations.
41 * Two main constructors are available:
42 * - the most simple one, taking directly a \ref meshes "MEDCoupling mesh" object
43 * - the second one (for an advanced usage), which can be used to specify an explicit topology
44 * in a parallel computation.
