What Are the Best Public Domain 2D Finite Element Routines?

AI Thread Summary
The discussion centers around finding suitable finite element routines for 2D applications, specifically for calculating the eigenvalues of the Laplacian operator on a 2D surface defined by a polygon. Participants inquire about the desired type of code, whether it should be general-purpose, open source, or simple for experimentation. Recommendations include Elmer, a comprehensive finite element software, and a reference to a resource listing public domain codes with source availability. The emphasis is on selecting between a complete package and a simpler code that meets specific application needs.

Does anyone knows some good finite elements routines in 2D?
 
Technology news on Phys.org
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 :

http://homepage.usask.ca/~ijm451/finite/fe_resources/node139.html

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.

Thanks a lot!

Thread 'Is this public key encryption?'

I've tried to intuit public key encryption but never quite managed. But this seems to wrap it up in a bow. This seems to be a very elegant way of transmitting a message publicly that only the sender and receiver can decipher. Is this how PKE works? No, it cant be. In the above case, the requester knows the target's "secret" key - because they have his ID, and therefore knows his birthdate.

Thread 'Who is responsible for the software when AI takes over programming?'

I tried a web search "the loss of programming ", and found an article saying that all aspects of writing, developing, and testing software programs will one day all be handled through artificial intelligence. One must wonder then, who is responsible. WHO is responsible for any problems, bugs, deficiencies, or whatever malfunctions which the programs make their users endure? Things may work wrong however the "wrong" happens. AI needs to fix the problems for the users. Any way to...
