X-Git-Tag: v9.4.0-rc1~792^2 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F13002%2Fhead;p=dealii.git Fix and augment documentation. Specifically, the picture shows four, not three hexahedra being subdivided. --- diff --git a/include/deal.II/grid/grid_generator.h b/include/deal.II/grid/grid_generator.h index 5269a6d0a4..18821ddeff 100644 --- a/include/deal.II/grid/grid_generator.h +++ b/include/deal.II/grid/grid_generator.h @@ -2020,14 +2020,16 @@ namespace GridGenerator * (quadrilaterals, hexahedra) to a triangulation only consisting of * simplices (triangles, tetrahedra). * - * As an example, the following image shows how a set of three hexahedra - * meshing one eighths of a sphere are subdivided into tetrahedra, and how + * As an example, the following image shows how a set of four hexahedra + * meshing one eighth of a sphere are subdivided into tetrahedra, and how * the curved surface is taken into account.
