[Scilab-users] topological optimization

[paul.carrico at free.fr]

Hi Christophe,

I've found interesting reports (in french) on the use of Finite elements solver in conjunction with matlab in order to solve topological optimisation using homogenization method.
http://www.vrince.free.fr/PE_optimisation/

Furthermore we can see some examples of the use of Scilab:
http://www.cmap.polytechnique.fr/~allaire/levelset_en.html
http://www.cmap.polytechnique.fr/~allaire/freefem_en.html (+ freeFEM)

Another interesting link (with Matlab programs) :
http://www.topopt.dtu.dk/

Unfortunately (as imaginated), the mathematical theory behind is not trivial … “crazy, I said crazy  ... well it's not the excat word :-)))))

What yo need is an interface between a CAD software and your FE solver,
because you have to modify the 3D model and feed your FE solver
which then has to define a new mesh.

Commercial solutions often offer this kind of link,
and even feedback between FE solver and CAD with automatic
optimisation possibilities.

However, I don't know how Scilab could play a role il this process.
