help with integrated nastran in osd

[rapa]

after several attempts I failed to launch analysis of a frame(group) made with tubes (+parts) shaped with enclosures (shell) I can't create the bond between the parties!! !
Is it possible or should I make the frame in one part??
If you can help me thank you very much

I think it's possible, but I don't know the osd solutor well...

an observation: it is preferable to avoid the maucine in the forums (equival to shout )

from what I read is not a problem of solutor (Matthew) but is a problem related to pre-processor fem in osd.
by experience when in a pre-processor fem integrated in the cad you can not get a congruent mesh (I imagine that is your problem, rape) you have to work at the level of geometry, trying to make sure that the surfaces are congruent.
the solutor will then analyze the model that passes him.

My problem is that if the surface with which the frame is not formed by a single part you create so many mesh how many parts are but these are disconnected between them and you can not do the analysis ...probably the command I look for does not exist. .

exists, you must connect the faces of the various pieces.
