This document describes the AMDiS Refinement Hierarchy 2 (ARH2) File format, version 3.0. The file format includes a description of the refinement of mesh-elements and value containers for the degrees of freedom (DOFs) for a given Finite Element. The concrete definition of finite elements is thereby described in a separate file format (AMDiS Finite Element Description (AFED) ) given elsewhere.
Historically the ARH2 format is based on the ARH format from 1970 (* placeholder for the actual date).
Historically the ARH2 format is based on the ARH format from 2010 (* placeholder for the actual date).

\begin{description}
\item[Version 3.0: March 02, 2015] Definition and description of Finite Elements was restructured and extracted from the ARH2 file format and put into a new file format. A new container format for parallel files (pARH) was added.
\item[Version 2.1: June 01, 2014*] A zlib compression for the file was added.
\item[Version 2.1: May 20, 2014] A zlib compression for the file was added.
\item[Version 2.0: January 01, 2014*] First official release of the ARH2 file format. The format consists of two parts, the \textit{header} and the \textit{body}. The header contains the general information about the content in this file, the format version number, the header size, dimensions, a macro table, an simplified Finite Element description and a value table. The header is followed by body structure for each macro element, which includes mesh structure code and DOF value vectors.

\item [Version 1.1, December 2010] Format description, as implemented in AMDiS.
\item[Version 1.0: July 29, 2010] First format description of original ARH file format. Implemented by MeshConv.
