Open Source

(OP)
Hello there,

I have been recently informed about an open source code, called salome, to realize fem structural analysis.
Has anybody of you ever heard about this code ? Which are the differences with respect to traditional –and not free- codes ?
Why should one change from a standardized software – I don't know if I can post the name-  to move to a code as this ?
Are these softwares equivalents ?

Many thanks
 

RE: Open Source

Heard of it? Yes. Tried it? No.
From what I gathered by looking at it, though, Salome is a pre/post processor. It can be used with many FEA solvers; two popular solvers are Calculix and Code-Aster. I think that you'll find that these tools will work for simpler problems, but you'll probably take substantially longer to arrive at an answer than a commercial package will.
Overall, I think that the Salome project is quite interesting. Hopefully they'll eventually be able to compete with more advanced solvers. Good luck, and let us know what you find out if you try it.

RE: Open Source

It's included in the linux distro CAELinux, which you can put on a USB key and then boot into so you can give a try and see.

I've tried it but I haven't used it enough to give a thumbs up or down, but as long as you looked at the capabilities and they match up with what you need it is definitely worth a try.

Greg,
Yeah, solve time matters. As computers get faster, models get bigger and more complex. Contact, radiation, plasticity, and other nonlinear problems used to be avoided at all costs, but now are commonplace. C'est la vie.

Flash, I agree with your statement (unfortunately), but who hand on heart can really say that they fully understand all the physics behind such "multi-disciplinary" analyses?

IMHO running analyses without a "feel" for the results you expect to see and some means of a sanity check is just a recipe for a disaster.
