From: Jaeryun Yim Date: Mon, 11 Jan 2016 10:55:45 +0000 (+0900) Subject: Add some tests for the P1 nonconforming nonparametirc element. X-Git-Tag: v8.5.0-rc1~624^2~38 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=92f82d92208d969f9b822a826f438ec35b8bc3e5;p=dealii.git Add some tests for the P1 nonconforming nonparametirc element. They are shape value and shape gradient tests on a square, a rectangle and a parallelogram. These results must coincide with the results of the parametric version. --- diff --git a/tests/fe/p1nc_nonparametric_01.cc b/tests/fe/p1nc_nonparametric_01.cc new file mode 100644 index 0000000000..357b1fd2e1 --- /dev/null +++ b/tests/fe/p1nc_nonparametric_01.cc @@ -0,0 +1,77 @@ +// --------------------------------------------------------------------- +// +// Copyright (C) 2015 by the deal.II authors +// +// This file is part of the deal.II library. +// +// The deal.II library is free software;
