Hi Khaled,

In my opinion, Gmsh would be an ideal fit for your requirements and in most cases.

You can obtain it here: http://gmsh.info/

You can go through the documentation here: http://gmsh.info/#Documentation

Hope that helps!

Like discussion on FE solvers, what is best, I find, usually depends on one's intended purpose for the tool, i.e. it very much depends on whether you are after structural analysis, CFD, geometry scanning, etc.
