X-Git-Tag: v8.5.0-rc1~54^2 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9601029a65b0c6712d655c114961a1894de5aa34;p=dealii.git Simplify a geometrical check. Both branches currently throw an exception, but the second message is more descriptive. --- diff --git a/source/grid/tria.cc b/source/grid/tria.cc index 6a5ac44105..284169ef7a 100644 --- a/source/grid/tria.cc +++ b/source/grid/tria.cc @@ -1687,32 +1687,28 @@ namespace internal case 2: break; default: - // in 1d, a node must have one or two adjacent lines - if (spacedim==1) - Assert (false, ExcInternalError()) - else - AssertThrow (false, - ExcMessage ("You have a vertex in your triangulation " - "at which more than two cells come together.
