CFD programs

[rob]

I would like to start with some CFD simulation. I haven´t done it befor so I am looking for some demo version or some free software just for try it.
It will be best if it could work also with 3D models.
Can anybody help.
Thanks in advance!

hello everybody
This my first time from long time to write any thing here

About CFD Software, I think for a start it's better to use easy package like cosmos flow
but it requird that use solidworks as cad pack, Also CFX is a good one that
comes with tutorial but it's just asolver so you will need a meshing software so
I prefer that use Cosmos for a start.

But It's all up to you and if any one know something better.
