[scilab-Users] Particular optimization

[paul.carrico at free.fr]

Thanks for the so quick answer ... 

However I would like to MAXIMIZE and not minimize the stress mapping and I don't know if it's possible ...

But i'll take a particular look on your example ... 

Speak to you soon

Bye

Paul

Hello,

I joined to this mail an example of such a thing performed using code 
aster and scilab.
The script to be launched is launch_optim.sce. Be careful, you will need 
to set up some paths in this script.

The optimization problem is the following: optimize the shape of a truss 
bridge so as to minimize the deformation of the deck of the bridge.
