<DL COMPACT><DT>Example:
<DD>
A plot of a  two-dimensional mesh and its deformation, obtained via <b> TRMCXX</b> is given in
figure <A HREF="#figtrmaco1">3.1</A>. It corresponds to test example 2 of a two-dimensional elasticity problem with
plane deformations described in  [<A HREF="node109.html#guide1"><A NAME=tex2html331 HREF="../Guide1/welcome.html">MODULEF User Guide - 1</A></A>]. The deformations are amplified by a factor 4.,
which is displayed in plot  window F4.

The  plot was obtained by typing the following sequence:

A default value  is proposed for each option.
The above table lists the selections made automatically when plotting the isovalues. Type 0 to
obtain the plot.
<P>
A key (a number)and a status correspond to each item. To modify the status, it suffices to type the
key and enter the values corresponding to the status desired  (see the general introduction).
The list of keys is given below:
<P>
<DL COMPACT><DT>Key 10:
<DD> the plot type: mesh and isovalues (default value).
<DT>Key 11:
<DD> already seen.
<DT>Key 12:
<DD> already seen.
<DT>Key 20:
<DD> already seen.
<DT>Key 21*:
<DD> the name of the file containing the solution (D.S. <b> B</b>).
To change files, activate this key and enter the name of the new file to  be consider.
<DT>Key 24*:
<DD> the load case to consider (1 by default). This value must lie between
1 and NDSM, the total number of load cases  present in D.S. <b> B</b>.
<DT>Key 27*:
<DD> array  B4 to consider (1 by default). This value must lie between
1 and NBBLOC, the total number B4 arrays present in the  D.S.
<DT>Key 32*:
<DD> the number of variational unknown to consider (1 by default), this value
must lie between 1 and NINCFV (see D.S. <b> MAIL</b>),
the number of  unknowns, and the  mnemonic of the unknown to be considered (VN by default).
<DT>Key 25*:
<DD> the number of isovalues (25 by default, value used for a black-and-white terminal). Activate this
key to change this value.
<DT>Key 26*:
<DD> the extreme isovalues. By default the minimum and maximum are determined
automatically as the minimum and maximum of the values contained in the D.S.
To change these values, activate this key and select only the part of the solution which is desired.
<DT>Key 72*:
<DD> the plot type for the isovalues (by default, in color if the terminal allows it, or
black-and-white if not). We have the following choice:
<PRE>   REPRESENTATION CHOICE:
     -1 : FIXED COLOUR LINE
      0 : COLOUR LINE
      1 : SHADED
</PRE>
<DT>Key 45*:
<DD> the choice of color spectrum (by default from red to blue). We have the following choice:
<PRE>   SPECTRUM ON 8 PLANE MONITOR:
   STANDARD  : RED TO BLUE           : 1
   RAINBOW   : RED TO MAGENTA        : 2
   THERMAL   : BLACK-RED-YELLOW-BLACK: 3
   MAXIMUM   : BLACK-COLOUR-WHITE    : 4
   BLACK AND WHITE                   : 5
</PRE>
<DT>Key 34*:
<DD> to associate a color with a value (specify, for each color, the value to associate with it).
<DT>Key 71*:
<DD> indicate isovalues  (no indications by default). Activate this key in order to
display isovalue numbers from place to place; in addition, the isovalues are plotted by changing the
line type modulo the number of possibilities.
<DT>Key 31:
<DD> already seen.
<DT>Key 30:
<DD> already seen.
<DT>Key 40:
<DD> already seen.
<DT>Key 50:
<DD> already seen.
<DT>Key 60:
<DD> already seen.
<DT>Key 70:
<DD> already seen.
<P>
<DT>Key 80:
<DD>  the type of plot lines desired for the mesh: solid (by default) or, by activating this key, the choice between:
<PRE>    SOLID      : 1  --   DOTTED    : 2
    DASHED     : 3  --   MIXED     : 4 ?
</PRE>
and for the isovalues (for an unmarked line plot) with the same choice.
<P>
 </DL>

<P>
Once a plot is displayed on the screen, a <i> graphics</i> menu appears, as for the other modules, 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 or M) (designate the zoom zone by clicking or designating manually), or a zoom- (6);
<LI>  <b> obtain the value</b> of a isovalue designated on screen (7 S F X A Z W);
<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>
The only new feature is the item to obtain the value of an isovalue. There are several ways of
performing this interrogation, described below:
<P>
<DL COMPACT><DT>(7):
<DD> click on a point in the mesh and validate by typing 7: we obtain (on the console)
the value of the closest isovalue plotted and its number, as well as   (still on the console)
the value of the clicked point (P1 interpolation) and its coordinates.
<DT>(S):
<DD> click on a point in the mesh and validate by typing S: we obtain (on the console)
the value of the closest isovalue plotted and its number, as well as (on the console and
on the clicked point in a color which differs from the background)
the value of the clicked point (P1 interpolation) and its coordinates (on the console).
<DT>(F):
<DD> click on a point in the mesh and validate by typing F: we obtain (on the console)
the value of the closest isovalue plotted and its number, as well as (on the console and
on the clicked point in the background color)
the value of the clicked point (P1 interpolation) and its coordinates (on the console).
<DT>(X):
<DD> the same as  (F), but the color in which the value is displayed is not determined.
<DT>(A):
<DD>  delete the last number entered on the screen. After  refreshing (4) the screen, all
the values present on the plot will be displayed except the last one.
<DT>(Z):
<DD>  delete all the values entered on the screen. After  refreshing (4) the screen, all
the values present on the plot will be deleted.
<DT>(W):
<DD> the same as (F), but the the number (and not the value) of the isovalue closest
to the designated point will appear on the screen.
<P>
 </DL>
<P>
<DL COMPACT><DT>Remark:
<DD> There could be some differences between the above description and the result  actually obtained
due to the terminal used (color, black-and-white, ...), the type of visualization selected (lines or
shaded) and the precision with which the points are designated.
<P>
 </DL>
<P>
<DL COMPACT><DT>Example:
<DD>   The example shown in figures <A HREF="#figtrmaco2">3.2</A> to <A HREF="#figtrmaco2c">3.4</A> corresponds
to a plot of the isovalues of the displacements in x-direction of the problem considered in test 2 of
[<A HREF="node109.html#guide1"><A NAME=tex2html331 HREF="../Guide1/welcome.html">MODULEF User Guide - 1</A></A>]. The first plot is produced without the isovalue markings, but by
clicking (action (S) in the graphics menu) on certain isolines such that the corresponding value appears on
the screen. The second plot includes the isovalue markings (note that the
line type changes from one line to another).
The third plot is done on a color terminal and sent as a softcopy to a black-and-white
postscript printer.
<P>
The plots were obtained by typing the following sequences:
