which software fem?

[rapa]

Is there anyone who can give me indications about free software to use in the company to make structural analysis of carpentry frames?
so analysis using shell elements!
or is it better to leave? Thank you.

first you have to understand if you have the basics of fem and who knew how to operate you. then you can use salome or other simulators. There are so many. You have to understand what you know and how you intend to learn.

The question is a little strange. Very strange. Do you want freeware fem software or do you want to quit? How do we know if you're able or not?
in any case I would try with this:http://www.calculix.de/

if you want to use calculix I suggest you try freecad even in the developer version if you want where there is integrated the fem module with calculix motor. then you can download the full calculix on the other site that you will use for the complete view of the results.

Actually, I do fem on electro-welded and/or mixed tubular carpenters but my mesh are always solid, never shell, never simplifications with beam effect. I love to see the subject that deforms even locally and leave the evaluation to me in those areas.

Until now I have used intergrated nastran in creo\direct, but following a future update of the cad probably will not be purchased anymore.
we asked an expert (polytechnical milan test) and said that current program is not indicated for analysis frames that have a small thickness since shell elements on axiemi cannot be implemented with this program.
Solid elements require too much memory to be analyzed using mesh with dimensions at least half thickness.

leaving aside in the sense of continuing to use the commercial program, I don't think it's easy to use learning to use a free program.

if you have a good base and a little dimwstichezza, you can implement equal techniques on different programs, especially if they are at graphic interface and not codes to write.
Let's mean....make fem with programs where there are buttons to put constraints, forces and options is definitely easier suspect than you write text codes to fill out.. . .

Hi, you can try using shareware version of edisis newsoft, specific for the design of buildings in c.a. see the following link:
