21 * \brief Relocate nodes to lie on geometry
22 * \param [in] theInputMedFile - a MED file holding a mesh including nodes that will be
23 * moved onto the geometry
24 * \param [in] theOutputMedFile - a MED file to create, that will hold a modified mesh
25 * \param [in] theInputNodeFiles - an array of names of files describing groups of nodes that
26 * will be moved onto the geometry
27 * \param [in] theXaoFileName - a path to a file in XAO format holding the geometry and
28 * the geometrical groups.
29 * \param [in] theIsParallel - if \c true, all processors are used to treat boundary shapes
