Have I modelled the boundary conditions correctly?

[cagosi4788]

This is the mechanism I am trying to model, movement is hindered in the XYZ direction, and it can only rotate in one direction as seen below:

Ive modelled it as a beam at an angle connected to a vertical beam. Both ends of the beam have the mechanism seen in the first picture. I have pinned the bottom of the beam but allowed for rotation in the Y-axis. The top of the beam Ive put a linear release, which allows for rotation in the Y-direction. Could this be the right way to do it?

Hi @cagosi4788 

You have used support and release definition. Support is defined in global system of coordinates while releases in local bar system. I do not see local bar system so I cannot be sure about release, but In support definition you should switch off RX not RY (as presented).

I have turned on the local axis for the member; does the linear release look correct?

Hi @cagosi4788 

It is correct definition. You can also fix both bottom supports and define release Ry-Ry at sloped bar both ends. Results should be the same.
