BTW, you also can use ODE.2, a wrapper for ode2, with preprocessing of the equation switched off.
Also, you can specify the initial conditions in Solve using Davide's at().
Thank you, just forgot about it out and found it afterwards.

Yet another example from the maxima discussion list. It demonstrates use and limitations of the solver function Solve().

The Maxima draw package has an experimental interface to the VTK visualization toolkit. It provides high performance 3D rendering.
Objects and options are very similar to those of the Gnuplot interface in the commands Draw2D() and Draw3D().
The current state of the Maxima plugin allows you to play around with VTK. Some limitations apply:
- The interactive viewer is opened as a separate window (not embedded in the sheet)
- The Maxima plugin does not wait for the viewer to be closed but gives up after some short time.
- Any SMath action while the viewer is open can generate a crash.

Thank you Martin with keeping this up 
I just played a bit (see the picture, please). I suppose this will be improved and I wish you all the best of luck in your efforts.
In the case I did not do something wrong here, but it seems that my example produces additional gnuplot windows.

This is related to issue SS-189. Maxima is restarted and the plugin retries to execute the command. However, in the new Maxima process, the variable draw_renderer has the default value (gnuplot) instead of VTK.

If the image file format is set to png, then the plot functions provide enhanced text capabilities now. See the attachment.

In the attached sheet you find the construction of the element stiffness matrix and the element load vector for a shear-stiff plane horizontal beam finite element as used in this example.

Example for beam calculation using separate integration intervals.
Hello,
I tried to use this method on a simple case with triangular distributed load.
I got the correct results for V and M moment but not for w and rotation (file1).
Using the same equations but divided into two separate systems ( equilibrium and elastic line) the result is correct (file 2)
anyone can give me any suggestions?

This example produces Asby material property charts. The data has been taken from the online ressources for Buchmayr 2002. Besides the Maxima plugin and it's drawing functions this program also demonstrates the use of varous plugins by Davide (ComboBox List, DataExchange, Checkbutton List)
