[ff3d-users] a beginner's question

[p***@siemens.com]

Hi,

One of my friends just recommended freeFEM++ to me. Does ff3D has the
same functionality as freeFEM++ (a 2D version?)? I noticed that the
latested freeFEM++ was released in Oct 2007, while ff3D seemed has an
older update.

I have very complex geometries. Can ff3D handle meshing of very complex
geometries?

Best Regards,

Pei

freefem++ has more functionalities, but you can solve a lot of problems using
ff3d... It depends on what do you want to do ...

ff3d does not incorporate any mesher. But there are two ways to deal with
complex geometries in ff3d:
- use the fictitious domain methods, or
- use the standard finite element method using an existing unstructured 3d
mesh of tetrahedra (you can build it with gmsh for instance)
