Mesh\+::\+Get\+Element\+Transformation(element, transformation), safe in concurrent element loops. 

\begin{DoxyNote}{Note}
MFEM\textquotesingle{}s version gathers curved-\/mesh nodes through Finite\+Element\+Space\+::\+Get\+Element\+VDofs(int, Array\&), which writes the space\textquotesingle{}s shared mutable Dof\+Transformation. This copy performs the same steps with a local Dof\+Transformation, so the transformation and every value derived from it are identical.

Call body(index, worker) once for every index in \mbox{[}0, count), possibly concurrently. 

\begin{DoxyNote}{Note}
Results do not depend on the thread count when each call writes only index-\/owned results and scratch owned by its worker (0 \texorpdfstring{$<$}{<}= worker \texorpdfstring{$<$}{<} \doxylink{namespaceserif_1_1utils_1_1parallel_a845c655da35a46d0be87880f0e4fa2d9}{worker\+\_\+count()}). Every index runs; the exception of the lowest throwing index is then rethrown, which is the one a serial loop would have raised.
