Requests calculation and ouput of gradients of the fields from the Hardy transfer class. These gradients will be with regard to spatial or material coordinate for eulerian or lagrangian analysis, respectively, as specified by atom_element_map (see <a class="el" href="man_atom_element_map.html">fix_modify AtC transfer atom_element_map</a> ) <h2><a class="anchor" name="restrictions">
