problema con tensione von bets

[claudio90]

Hello everyone, my name is claudio, I am a new member (I just sent my presentation) and I am an ansys neophyte. I wanted to ask you a hand for a problem that I can't solve.

I modeled a frame by joining keypoints with lines and used as beam188 elements.
I think I've done all the steps of the case and I finally solved the structure.
when I want to view the movements (contourplot->nodalsolu->dof solution->displ.vectorsum) I have no problems, while if I ask to view the tension of von mises (always in contourplot->nodalsolu) I see the following message:

"beam/pipe elements are detected in the selected element set. they are ignored in the nodal havingaging"

and the structure remains white. it happens the same for any tension I want to display.

I imagine that the problem is trivial and easy to resolve, but as I said, I am really at the very first weapons with this software and I would be grateful if anyone could give me an indication.

thanks to all and good day.

mail the log file so you understand better.
selected the material? made mesh?applied loads and constraints? ?

per quanto riguarda i passaggi che mi hai indicato (materiale, mesh, etc..) credo di aver fatto tutto, ma potrei sbagliarmi.
grazie mille per l'aiuto.

so you do not solve anything in the sense that you post only a part of the .log file.

Are you doing one of the pasm course exercises?

 

[claudio90]

Yes, exactly... that should be the first. the problem is not so much exercise in itself, because I am with the movements, the binding reactions, etc...the only thing about the display of tensions, with the appearance of the warning that I reported in the first post...
