mpc184 the element

[enrico1979]

Bye, guys.

I'll probably be tough on my head, but the more I read the classic and the more I'm confused.
the problem that I posed was to simulate a zipper that I conceptually believe (I know how to do but I still run examples) of having solved thanks to your advice and a long research on the help.
but new questions have emerged from this research where the most banal (and for this reason makes me nervous) is to understand where to find the element mpc184 (which initially, given the characteristics I believed could be useful for the hinges but that it is not actually).
in the guides read mpc184 link|beam etc.. but how to understand how to identify it and assign it in an exercise nothing.
the help is complete but too many are the books related to mechanical apdl and if you advised me from which to start (to have a first general infarinate) I would be grateful. I am also reading the mandeci to have a comprehensive view of the software summed up in a number of reasonable pages, but it is actually insufficient. if to learn well such software it is necessary to read 10000 pag, then I will read 10000pag.

forgive me if I stress you and thank you in advance

bye

advice: let him lose at the moment .. is a somewhat ostic element .. and that's why you find little or nothing. an intense use is done when simultaneous cinematisms and other strangeness. in fact if you open the ansys help and enter mpc184 you are offered + exercises ... vm239,vm240,vm258,vm179 and more ... then good work

Perhaps to simulate a hinge, at least in the plane, it would be easier and intuitive to create separately for example two beams with two overlapping ends (but not coincident). then go to couple the degrees of freedom ux and uy leaving free rotation.

Hello stefano.
test also endrelease works very well.

Thanks for always running in my help.

relative to the hinge I will try both the methods recommended by you, considering also that I finally identified a bit of literature asking in search of the help...." what is coupling " that leads to the cap 12 of the book, modelling and mesh guide.
I know that what I wrote to you two does not need, but for those who read our discussion and asked my own questions, it could find useful as written above.
In this way I hope to also give my tiny contribution to learning this software,
As for the mpc182, I found it in the list of the constraint group, but with the not linear activation.
at the moment I follow cmq the advice of eih64 and I leave to lose going forward by degrees, otherwise I risk nn understand more nothing.

bye and next

right, very convenient command. I forgot because I rarely use beams. Thank you!
