This record activates global mesh refinement or global mesh coarsening. This is not available for -tria3 and -tet4 elements. Either refinement_method is -h_refinement (more of the same elements) or refinement_method is -p_refinement (higher order elements) or refine_method is -p_coarsen (lower order elements).
As a special option for the -h_refinement method, the format refine_globally index -h_refinement switch_ switch_ switch_ can be used. By example in 1D, only refine_globally index -h_refinement switch_ should be specified. By example in the -hex8 element, is the isoparametric coordinate running from the first node to the second node, runs from the first node the third node and runs from the first node to the fifth node. A isoparametric direction will be refined if the corresponding switch is set to -yes. This option allows for refinement in specific directions. It should be used with care however, and only gives proper results if the , and directions of the elements match.
The control_mesh_refine_globally will automatically merge nodes which have the same position in space.
