   An example is that \texttt{DiscreteTime} ensures that the final time step ends

+  respectively~\cite{BangerthHartmannKanschat2007}. This release now
+  contains a class \texttt{FEInterfaceValues} that considers the

+  allows evaluating jumps and averages of shape functions along this
+  face. These are common components of the bilinear forms of

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
