Finite elements routines in 2D

[Estrellita76]

Does anyone knows some good finite elements routines in 2D?

Could you elaborate a bit, are you after something for a particular application, a general purpose code, open source codes, something to 'just' play around ...?

I am looking for code. I would like to calculate the eigenvalues of Laplacian operator over a 2D surface, the border given as a 2D plot (polygon). Thanks in advance.

Public domain with source are listed pretty good at :

bunch of them will do the job, suppose it's a question whether you want to work with a fairly complete package (like elmer for one, but am biased in recommending it :approve: ) or a code which is a short and simple one and will just do the job for your application.
