which software fem is better?

[vale_85]

Hello everyone,
It is the first time I write here even though I often read this forum and I have often been helpful.
I am graduating in management and I am doing thesis; I need your opinion.
I have to make a fem simulation of a cryogenic drilling in 2d and the important points in choosing the software that will then acquire the university are qesti:

• it is necessary that the software detects phase transformations, i.e. injecting gas at low temperatures there is a change of material characteristics and the software should automatically detect it;
• how to represent stresses on the tool-piece interface
• if the software is 3d must be able to work in 2d, because all this will be done in 2d

Candidate software are ansys and deform, would you tell me the advantages of each and which one could be more suitable for my case?
Thank you:

I would use abaqus for personal experience, but maybe it's a bit out of budget.. .

but the brains of the university where they are?
Can they not know which software is the best? ? ?
Hi.

Hi.

I'm sorry. But it came to my head and I can't resist. . .
a university professor tired of his intellectual work decides to spend the holidays on a farm; in exchange for the accommodation will do some manual work.
the first day the farmer asks him to empty the manure at the bottom of the stable and to spread it on the field behind the farm. in the evening when the farmer returns from the camps he finds with great wonder the work already done.
the day after the farmer asks the professor to collect and count all the bales of hay present in the ground. at the end of the day when the farmer returns from the fields he finds the job perfectly done.
on the third day the farmer, ashamed of the heavy work proposed to the professor two days before, asks him to divide the big apples from the small and to discard the marches. When the farmer returns from the camps, with great wonder, he sees that nothing has been done and the professor with an apple in his hand saying: "is she small or big?"
moral: to spread shit or to contar dances all are capable, but when it comes to making a decision....

I understand your answers very well, but if I had omitted the fact that it is about the university you would have responded normally?
But if he had decided for me, what does a thesis do?
He told me to search for information about software, to inform me. It doesn't seem wrong, and I asked here because it seems like a well-stocked forum of people who understand it and so I could only learn from you.
Thank you.

Thank you.

strategic choices such as choosing a software instead of another should be entrusted to people with experience and competence of the branch. I'm surprised that your professor relies on a student, who, with all the good will, won't be able to distinguish between what a program can do and what it promises to do, if the student understands what he wants to achieve.
I tell you with the utmost respect, but I was also a student and I can now compare the skills I had then with those I have now (and I realize that at the time I understood very little).

I probably wouldn't have come up with that old joke and we'd have waited for some answers from the fem analysis experts.

Right.
In this case the prof.
You just joke about...

still just.
the approach is correct. It's always good to hear more bells and then make decisions
Mine was just a joke, nothing more.
I don't know about fem, so... I do not participate in the discussion except as "judging".

 

[vale_85]

mbt did well....the prof. did not tell me decide.... but look, study, informed, did not delegate to me the choice.
and I am a student who wants to know how much more to do a good job, so I would like answers on software, and not on prof. or other... .
p.s.

So... .
If you accept lid. . .

my personal opinion, so take it "cum granu salis" or "as a topic of conversation". . .

choosing a fem for a specific need, in my opinion, is like choosing a car only because once a year I go to the ikea to take a closet and then I need a large trunk.
the rest of the year travel alone or max with the shopping bag, but at that time... I have a big car.
According to me the correct approach, beyond the "examination text" is to take a sw that works well for 90% of the time of use. for the remaining 10% I can evaluate various solutions, including "self-built" codes.
Moreover, cryogenic punctures or determination of flame profiles or fuel speed within the jet of the motorcycle carburetor are things that perhaps with a generic sw can not be done. Maybe you have to "be a bone" by adapting mathematics to the theory of the specific case.

other thing that almost everyone forget is the passage of information between who designs and who calculates. in the office we have a calculation software that does not directly read my 3d models. touch to pass by neutral formats. It's not a drama, but a nuisance.

 

[gerod]

I, in his time, made myself make quotes and made me explain the potential of the various fems.
your request is not trivial and very niche.
I believe that you should contact the houses that market the sw.

Anyway, we were joking and not too much about me.
However the joke of mbt is excellent.

Thank you:

Your question is very specific I don't know if there's any user of the forum expert in the particular branch, try asking about this yahoo group:
http://it.groups.yahoo.com/group/fem-analysis/I hope not to violate the regulation by directing a user to another forum!

Bye.

That's true.

certainly neither ansys nor deform can do an analysis of this type.

they can do it only abaqus and marc, which moreover the one (abaqus) is the son of the other (marc).

However it is not a joke, in the sense that finding values to characterize such materials in such a way is not simple.

Finally that universities devote themselves to serial applications of commercial software! ! !

Good job
