Recommend FEM software.

[Lou Pecora]

I have been looking around the web at various free FEM software
(libraries, frameworks, UI's, etc.) for solving PDEs like Helmholtz
equations. I found two that look rather complete, well supported, and
with good documentation. These are,

OFELI (http://www.ofeli.net/presentations.html) - a C++ framework which
takes some programming in C++ (which I know).

freefem++ - a framework with a UI and its own programming language on
top of C++ code- lots of documentation and looks very mature.

It is hard to tell by just looking at these if either is worth looking
further into. Before spending that time, I thought I ask to see if
anyone has used the code and what they would recommend.

Thanks for any insight and information.
