+These benchmark examples test the implementation of
+thermohydromechanics process with analytical solutions
+presented by Vogel/Massmann.
+
+A detailed descritption can be found in the ogs Benchmark books.
+The following table links the ogs problem descriptions with its corresponding
+chapters in the benchmark books.
