<P>
A default value is proposed for each option. The above table lists the choices made automatically.
To obtain the corresponding plot, type 0.
<P>
A key (number) and status corresponds to each item. To modify the status, it suffices to type the
key and enter (see general introduction) the values corresponding to the desired state.
Some options are identical to those used for two-dimensional meshes and have therefore already been
described, and will thus be mentioned briefly only.
<P>
<DL COMPACT><DT>Key 10:
<DD> the plot type: mesh only (default choice), we can also request to
 visualize a mesh and its deformation: type 10 after which the program requests the
 name of the file containing data structure <b> B</b> of displacements.
 A number of additional lines then appears on the general menu (see below).
<DT>Key 11:
<DD> the device number.
<DT>Key 20:
<DD> the name of the file containing the mesh. To change files, we activate this key and input the
new file name.
<DT>Key 15:
<DD> the observation mode: longitude and latitude (default mode). By typing
15, we go from one mode to the other (viewed point, observation point) whose parameters are
accessible via key 17 and 18.
<DT>Key 16:
<DD> the observation conditions, i.e. the values of <IMG BORDER=0 ALIGN=MIDDLE ALT="" SRC="img60.gif"> and <IMG BORDER=0 ALIGN=MIDDLE ALT="" SRC="img47.gif"> (by default
 30, 30 and 10 degrees respectively). To modify these values, type the key number and enter the new values.
<DT>Key 31:
<DD> by activating this key, we can make inquiries about the mesh and obtain information regarding its contents.
<DT>Key 30:
<DD> the plot will be full screen, otherwise the user must specify the size in cm.
<DT>Key 40:
<DD> the type of characters plotted: hardware (by default), software if not.
<DT>Key 50:
<DD> the choice of items to plot: the triangulation (by default). By activating this key, we have a choice
 between:
<PRE>  -- INITIAL MESH                                 :
     NOTHING (CHECK ONLY)      : 0
  ** OUTER SURFACE EDGES (ALL) : 1
     OUTER SURFACE EDGES (VIS.): 2
     SURFACE EDGES (INVIS.)    : 3
     SHRINKED SURFACE (ALL F.) : 4
     SHRINKED SURFACE (SEEN F.): 5
     SHRINKED SURFACE (HIDDEN F.): 6
  ** ALL ELEMENTS              : 7
     ALL SHRINKED ELEMENTS     : 8 ?
</PRE>
<DT>Key 51:
<DD> only the edges not belonging to two adjacent  faces, coplanar (by default) w.r.t. the
coefficient contained in key 53, are not plotted. By typing 51, all edges are plotted.
<DT>Key 53:
<DD> the coplanarity coefficient (0.00001 by default), by typing this key the default value can be modified.
<DT>Key 54:
<DD> the faces are colored-in (yes, by default), type 54, to obtain the inverse choice.
<DT>Key 56:
<DD> orientation of the faces  (yes, by default). This signifies that during the elimination
of the hidden faces, we only plot the faces facing the observer. By selecting this key, the opposite
state is  obtained.
<DT>Key 88:
<DD> stereoscopy (no, by default), yes by typing 88 (if the terminal allows it).
<DT>Key 60:
<DD> the general legend (there is a legend by default) corresponds to the
indications appearing to the right of the plot (see examples: title, date, file name, ...). By typing
60, we specify that we do not want the general legend.
<DT>Key 70:
<DD> the numbers to be displayed, none (by default) or, by activating this key, the
choice between:
<P>
<PRE>    NO NUMBER          : 0
    ELEMENT : 1 - POINT: 2 - NODE  : 3
    SUB-DOMAIN         : 4
    REFERENCE (ALL)    : 5
    REFERENCE POINTS   : 6 - NODES : 7
    REFERENCE EDGES    : 8 - FACES : 9
</PRE>
<DT>Key 80:
<DD> the type plot desired: solid (by default) or, by activating this key, the choice between:
<PRE>    SOLID      : 1  --   DOTTED    : 2
    DASHED     : 3  --   MIXED     : 4 ?
</PRE>

Once a plot is displayed on the screen, a <i> graphics</i> menu appears which allows us to:
<P>
<UL><LI>  Exit (0) from the session,
<LI> Continue (1), i.e., return to the module's main menu;
<LI> Display the next (2) or previous (3) view;
<LI> Refresh (4) the screen;
<LI> Zoom (5);
<LI> Define a section (6) (action described below),
<LI> Move the observer to the right (R) , the left (L) , the top (T) , the bottom (B), closer (+),
further (-),
<LI> Produce a hardcopy (9) of the screen, or a softcopy (8) on another graphical terminal; having done this,
the user is returned to the initial state (of this <i> graphics</i> menu).
</UL>
<P>
All these options are identical to those seen in the two-dimensional case. Only the
<b> section</b> is specific. <IMG BORDER=0 ALIGN=MIDDLE ALT="" SRC="img46.gif"> and <IMG BORDER=0 ALIGN=MIDDLE ALT="" SRC="img45.gif">, the observation and view points remaining unchanged, we enter
the sides of the two planes which is used to limit the part of the object to be displayed (by
default the two sections are positioned at <b>0.</b> and <IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img61.gif">, which corresponds to viewing the entire object).

<DL COMPACT><DT>Mesh and deformation:
<DD>  
<P>
The module (see utilization limitations) enables us to visualize a mesh and its deformed state. The
deformed mesh is obtained by adding (with an amplification factor) the calculated displacements
to the nodal coordinates.
<P>
For those cases possible, the selection of key 10 results in a general menu which is identical to that of
<b> TRNOXX</b> for the two-dimensional case, to which the reader is referred.
<P>
<P>
<P>
<DT>Examples:
<DD> Some examples of plots of three-dimensional meshes, obtained via <b> TRNOXX</b>, are shown in
figures <A HREF="#figtrgeom1">2.9</A> to <A HREF="#figtrgeom5">2.13</A>. Note that the graphics menu does not appear
as the figures correspond to a softcopy performed on a laser printer,
and as this terminal does not have any input possibilities.
<P>
<P>
<P>
The plots were obtained by typing the following sequences:
