Post New FEM software for acoustics - please try it out

Dear DIYaudio users,
I would like to invite you to try out a piece of software I've been working on.

It does 2D finite element modeling on acoustic systems. The main objective was to investigate the wavefront shapes (and thus directivity) produced by different horn profiles - I seemed to find very little information on the subject online.

To give you an idea, it's a lot like the wavefront simulator in Hornresp, just with more bells and whistles.

It's in a beta state at the moment. There are definately some problems with the physics, but I'm not enough of a physicist to know how much these limit the application of or otherwise invalidate the results. Input would be welcome.

That said, I don't anticipate doing a lot of work to this programme in the short term - chiefly because I'd like my life back. I'm certainly not planning to add any major features, but bug fixes - especially those related to the accuracy of the results - will be noted and incorporated in due course.

I'd love to hear your thoughts and experiences.

Don't Fear the Repair
