problems with constraints

[SimoneF]

Hello everyone,
I just started using sw simulation 2014 and I have a problem (I believe banal) with the application of some constraints. . .

in my case I have a structure composed of beams and pillars that the software considers as trave elements during the simulation phase (structure visible in the figure below):at the bottom there are four small supports that I decided to bind as fixed geometry:after which I applied a load per unit length of 100 n/m to these three components: made this provide meshare as visible in figure (above I meshato the surface by shell):starting the analysis the system converges and gives me its results only that a "short fact occurs": it is as if some beams are detached from the supports and others instead remain attached. . .How come? What did I do wrong?

thanks in advance.:smile:

If they break off it may be that the 3d model is done badly or the stresses are too other. Usually if it happens there's something wrong. you can go to consider how money you pull them and see if the problem persists.

actually using solid elements this problem is eliminated and the beams remain solid with the media, so how could I eliminate the problem using beam elements?

there must be something wrong as the union of the beams or contact group not right
