+ * \param [in] file - name of the MED file
+ * \param [in] theMeshName - name of this mesh
+ * \param [in] theAutoGroups - boolean parameter for creating/not creating
+ * the groups Group_On_All_Nodes, Group_On_All_Faces, ... ;
+ * the typical use is auto_groups=false.
+ * \param [in] theVersion - defines the version of format of MED file, that will be created
+ * \param [in] meshPart - mesh data to export
+ * \param [in] theAutoDimension - if \c true, a space dimension of a MED mesh can be either
+ * - 1D if all mesh nodes lie on OX coordinate axis, or
+ * - 2D if all mesh nodes lie on XOY coordinate plane, or
+ * - 3D in the rest cases.
+ * If \a theAutoDimension is \c false, the space dimension is always 3.
+ * \return int - mesh index in the file
