+Class
+    Foam::createShellMesh
+
+Description
+    Creates mesh by extruding a patch.
+
+SourceFiles
+    createShellMesh.C
+
+    Extrudes into thickness direction.
+    - bottom faces originate from reversed original faces (have turning index)
+    - top faces originate from original faces (no turning index)
