| 7 | 7 | Split {{{Info}}}'s grid into sub-grids using the [http://http://www-lmc.imag.fr/IDOPT/AGRIF/documentation/doc_AGRIF3DUser/node9.html Berger-Rigoutsos] algorithm. This algorithm examines cross-sections of the grid structure as a whole, looking for regions of cells marked for greater refinement (in this case, the cells have been marked by setting the error flag). when these regions are found, {{{NewSubGrids()}}} splits the grid into sections and creates subgrids around the refinable areas. Note that this subroutine does not create new [wiki:Node nodes] for the new subgrids, it just identifies them and stores data about them in {{{Info}}}. |
