<P>
A default value  is proposed for each option.
The above table lists the selections made automatically when plotting the velocities. Type 0 to
obtain the plot.
<P>
A key (a number) and a status corresponds 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 velocities (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 29*:
<DD> the maximum arrow size (2 cm by default). This value can be changed by activating this key.
<DT>Key 28*:
<DD> the type of arrows. The manner in which the arrowheads are plotted can be
specified as follows:
<PRE>   EXTREMITY OPEN , NORMALISED : -1
   EXTREMITY CLOSED , NORMALISED  :  1
   EXTREMITY OPEN , FIXED      : -2
   EXTREMITY CLOSED , FIXED       :  2
</PRE>
The arrowhead is open (2 lines) or closed (a triangle), and its &quot;length&quot; is calculated as a function
of the size of the arrow (which is related to the velocity modulus)  or fixed (for all the arrows)
to a value specified by the user.
<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 and arrows:
solid (by default) or, by activating this key, the choice between:
<PRE>    SOLID      : 1  --   DOTTED    : 2
    DASHED     : 3  --   MIXED     : 4 ?
</PRE>
<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 execute operations
(0), (1), (2), (3), (4), (5 or M), (6),  <b> (7 X A Z)</b>, (8) and (9) already described.
<P>
The only new feature is the item to obtain the value of a velocity. 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 velocity at  the clicked point (P1 interpolation) and its coordinates.
<DT>(X):
<DD> the same as  (F), but an arrow representing the calculated velocity is displayed in
the screen.
<DT>(A):
<DD>  delete the last arrow added to the plot. After  refreshing (4) the screen, all
the arrows present on the plot will be displayed except the last one.
<DT>(Z):
<DD>  delete all the arrows added to the plot. After  refreshing (4) the screen, all
the arrows present on the plot will be deleted.
<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> Figure  <A HREF="#figtrmaco3">3.5</A> is nothing other than the representation of the displacements of the
problem considered in test 2 in [<A HREF="node109.html#guide1"><A NAME=tex2html331 HREF="../Guide1/welcome.html">MODULEF User Guide - 1</A></A>], using the deformation option in terms of the velocities.
<P>
The plots were obtained by typing the following sequences:

<P>
A default value  is proposed for each option.
The above table lists the selections made automatically when plotting the cuts. Type 0 to
obtain the plot of the mesh  on which we can define a cut via item (7) of the <i> graphics</i> menu or via
key 37.
<P>
A key (a number) and a status corresponds 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 cuts (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 37*:
<DD> the cut selection mode. By default automatic, i.e. the cut is chosen by clicking on
the screen. By activating this key, we can input the coordinates of the 2 extremities of the  cut explicitly.
<DT>Key 38*:
<DD> the number of the variational unknown to consider (1  by default), this value
must lie  between 1 and NINCFV (see D.S. <b> MAIL</b>),
the total number of unknowns, and the mnemonic of the unknown under  consideration (VN by default).
<DT>Key 39*:
<DD> the solution function to plot on the cut. The user has the choice between:
<PRE> 1 -- FIELD OF VALUES      : VC
 2 -- DERIVATIVE IN X      : DX
 3 -- DERIVATIVE IN Y      : DY
 4 -- GRADIENT MODULUS     : GR
 5 -- ALPHA * DX           : ADX
 6 -- ALPHA * DY           : ADY
 7 -- ALPHA * GRADIENT     : AGR
</PRE>
The user enters the number of functions to be considered, and for each its type (between 1 (default choice)
and  7 (<IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img2.gif"> must be input if the choice is 5, 6 or 7)). As many curves will be plotted
as functions input.
<DT>Key 31:
<DD> already seen.
<DT>Key 30:
<DD> already seen.
<DT>Key 40:
<DD> already seen.
<DT>Key 50:

<DT>Key 60:

<DT>Key 70:
<DD> already seen.
<P>
<DT>Key 80:
<DD>  the type of plot lines desired for the mesh and cuts:
solid (by default) or, by activating this key, the choice between:
<PRE>    SOLID      : 1  --   DOTTED    : 2
    DASHED     : 3  --   MIXED     : 4 ?
</PRE>
<P>

<P>
Once a plot (mesh only) is displayed on the screen, a <i> graphics</i> menu appears, as for the other modules, which allows us
to execute operations
(0), (1), (2), (3), (4), (5 or M), (6), (8) and (9) already described.
Option (7) is used to define the cut line:
<P>
<UL><LI>  Cut (7): to define the cut line. place the cursor on a point on the screen and validate
by typing 7 to enter the first extremity of the cut line.
Perform the same operations  to enter the second extremity.
</UL>
<P>
A question then appears on the screen:
<P>
<PRE>   VOULEZ VOUS PRECISER LES AXES (OUI-NON)
</PRE>
<P>
A negative response results in a automatic plot of the cut.
<P>
A positive response results in the following sub-menu:
