search software for finite element analysis

[serby]

hello to all, my name is savior, I am architect and I work on design of pleasure boats.

I write to you because I'm looking for a software for finite element analysis that allows me to work on materials such as fiberglass, carbon, wood, in short, everything.

I press that I have little experience on the subject, so besides learning the program, I should document just about the type of activity, but the thing does not scare me. exist software we say "intuitive" to make these calculations? ? ? ?

inventor, catia, could they do for me?

hello to all and thanks

Well, there's a lot of them. .
but if you place on the inv forum, they will answer you ansys that is already integrated in the "pro" version of inv....

This is serby,

Beyond saying that ansys could do to your case like many other systems, it is to understand something more.

1-Do you have a cad 3d model? with what system was built? the cad 3d model can help you to build the fe model, especially in the early stages, then, going to detail the model, the cad can create you more problems than benefits, and often I also used a fe modeling detached from the cad.

2-For the problems of boats, you need in a first phase of linear analysis, with particular attention to materials however in composite, then you can need to face non-linear problems, not only for detailed modeling of materials, but also to verify the construction processes necessary to realize your boat.

3-for a detailed design of the boat, you must also deal with issues related to the life of the boat itself, problems of cracking/delamination of the materials used etc.

It is therefore right to start with "intuitive" tools as you ask, but also take into account that they are extensible to address the issues described that are those that will differ the quality of your project, and therefore of the boat, compared to other existing solutions.

in my opinion if the question is

"Are there software we say "intuitive" to make these calculations?? ? ? "

the answer could be: any software could go well, as long as used by those who have experience of structural verification fem.

Crazy weirdo.
then we say that the cost aspect is not to be underestimated and I imagine that going on not to line the costs lie quite a lot.
to make an example, those of ansys double (at least from the last quote I was made to pass from ds to pro version): I think the same applies to other software that I know little.
Then put a nice course and I would say that the figure is around 2x10^4 heuri.
alternatively there is salome (free) but here we are not on the intuitive.
Hi.

All right, guys.

first of all pleasure to make your acquaintance.......and as to "knowledge" on the topic....... well.... I couldn't find better!!! ! !

You already gave me some really interesting info. In short, I have to tell my boss to buy one of these software and predict to do a course because there will be, I think. what software do you recommend?

they had told me about catia v5, to which they are also adding a specific module for stability calculations, baricentres, change of trim after adding weight, etc.............I do well???? or inventor of autodesk?
or which others do you know?

to model use rhinoceros 4, great, but sometimes generates not so good surfaces. Here, once modeled I would like a program in which to insert my model 3d, tell him what material is made, with the due modules of resistance etc., to apply it a beautiful series of disollecitations and see if the structures of the fund maybe have been well sized, or the blanket is thick enough to resist to twist efforts..........and clearly I tell you this because I don't know anything about these programs.

you are kind

that I know I inventor leans on fem modules as well as catia (I believe that someone contests me)
So you need a form that goes from rhino to fem.
Maybe you need a fem module using shells (surface elements).
to see well, especially (I insist) how much you want to spend.
I would say that less than 10 thousand euros find little.
Hi.

 

[Matteo]

there would also be the basic modules of promecanica (integrated to proe, to stay around or just over 10000€) and neinastran (integrated to solidworks, less than 6000€), but you must first understand what are the minimum characteristics that the software must have to meet the needs of simulation, and secondly the maximum complexity that the company staff can manage.

I give you an example (of the far 2001, is the summary of my thesis) of optimization of the carbon structures of the hull of a sailboat, carried out with promechanica 2000i2

Hello, serby.

from rhino, even without having beautiful surfaces, you can use patran, which still allows you to put in place the gemotria if you need, without spending on a cad.

an interesting reference is:http://www.mscsoftware.com/success/details.cfm?sid=360&z=181&q=286take into account the courses, however indispensable and that they will be what you really buy. any product is useless, even that costs little (or nienete), if they do not teach you.

if you want to see something, even regarding how the courses are made, you can go to:http://www.youtube.com/user/simulatemorecation
