+<li><b>To remove the initial central point</b> TetMesh-GHS3D adds an internal point
+at the gravity centre of the bounding box to speed up and to simplify
+the meshing process. However, it is possible to refrain from creating
+this point by using the command line option -no initial central point. This can be
+particularly useful to generate a volume mesh without internal points at all and in some rare cases
+at the boundary regeneration phase when it is impossible to proceed
+with the standard options
+(for example, when one dimension of the domain is more than 20 times greater than the other two).
+Use this option if the boundary regeneration has failed with the standard parameters and before using
+the recovery version (command line option -C).
+Note: when using this option, the speed of the meshing process may
+decrease, and the quality may change.
+Note: the boundary regeneration may fail with this option, in some rare cases.</li>
