The standard CodeAster package comes with its own built in plotting ability.  The commands for creating the output when embedded into the *.comm file, will create the output.  We just need to tell ASTK to assign the results to a logical unit (LU=29) and a suitable output file name assigned with 'R' (i.e. Result).  I normally use the extension <*.agr> for this output file. Any name and extension should work, I think.

This tutorial shows how to set up the comm file.  Let us use the very nicely written tutorial by Kees Wouters as a base [http://www.caelinux.org/wiki/index.php/Contrib:KeesWouters/dynamicload].  That tutorial shows you how to conduct a modal and a forced dynamic response of a simple cylinder.  The resulting plots of that tutorial were perhaps created using a spreadsheet or another such plotting tool.

===Why XMGrace ?===

== CodeAster: ASTK Mesh Converter ==
−
Why do I recommend XMGrace?  Because it is easy to get plots once the command file has been set up.  Thereafter it requires just 3 clicks in the ASTK window.  One on the file name '*.agr', the second on 'Tools' and the third on 'Grace'.  The immense benefit is, one can see very quickly graphically, if the results are what you expected.

Of course a speadsheet, octave, gnuplot, etc. has features that far exceed the plotting capabilities of XMGrace, I believe.  But there's nothing to beat the handiness of plotting with 3 clicks!  Especially when one is making several runs or a parametric study.

The explanation of this command is:

−
# Load into function Dz the nodal displacement values from table TB_nodf, values from column: DZ (Displacement Z) for each INST (Time step). Resulting in tuples where

#        X values = Time Step instant
+
−
#        Z values = the corresponding displacement in Z direction

−

−
  T=RECU_FONCTION(TABLE=TB_nodf,

                  PARA_X='INST',

                  PARA_Y='INST',);

# Load into function T the time step values from table TB_nodf, values from column: INST. Resulting in tuples where

−
#        X values = Time step instant
+
−
#        T values = Time step Instant
+
−
 
+
−
(This second step may seem redundant, and if somebody has a more elegant way please let us know here.  Essentially we are creating two arrays T & Dz which contain the time instants and corresponding displacements of the top node in the Z direction.)

Then output T versus Dz for plotting with XMGrace
