\n GHS3DPRL Parameters hypothesis works only with <b>Tetrahedron (Tepal with TetMesh-GHS3D)</b> algorithm.
\n
\n This algorithm is a commercial software, its use requires a licence (http://www.distene.com/fr/build/offer.html).
-\n The advantage of Tepal is the possibility to generate (for example) a <em>partitioned</em>
-200 million tetrahedra mesh on a not-so-big memory computer (2Go RAM)
-...in something like 50 hours of <em>one</em> CPU (Xeon, 2008).
-This is an alternative to Pluging GHS3D where you should need something like a not-so-common CPU with 64Go RAM
-<em>to try</em> to do a one-partitionned 200 million tetrahedra mesh ...in a much less time indeed.
+\n For example, Tepal gives the possibility to generate a partitioned
+mesh with 200 million tetrahedrons on a computer with average memory size
+(2Go RAM) in about 50 hours on one CPU (Xeon, 2008).
+This is a serious alternative to GHS3D, which requires a much less common
+configuration with 64Go RAM to only try to make a partition of a mesh with
+200 million tetrahedrons, no result guaranteed.
\n
-\n Notes:
-\n This Plugin <em>doesn't</em> load in Memory the supposed plentiful big resulting meshes.
-It's user choice: (in GUI Mesh mode) menu File-Import-MED Files.
-\n Beware, to load one 5 millions tetrahedra MED file, GUI Salome needs 2Go RAM.
-\n A new true parallel faster version of Tepal, using MPI, is expected in 2009.
+\note The Plugin doesn't load in the Memory the supposedly large resulting meshes.
+The meshes are imported in the user-defined location as MED files via menu File-Import-MED Files.
+\n Pay attention, that Salome GUI Salome needs 2Go RAM. to load a MED
+file with 5 million tetrahedrons.

The default value of this parameter is 64 Megabytes and its
minimum value is 10 Megabytes.
