Hi all,

Looking for some assistance in regards to restraints in simulation. up until now i have only done basic simulation on single solid pieces and am currently working on an assembly that i am really struggling to understand where and how you apply restraints to give a real life simulation.

I have attached a screenshot of what i'm working on. It's a hose saddle for allowing hoses to bend over the edge of vessels that's being worked from. There are 2 main profiles that are connected by 6 pieces of angle. There are then 2 sizes of tubing inserted in between the 2 main plates. These tubes act as spacers with 1 size having rollers on them. There is then the main top hanging channel that is connected to the main arrangement via 4 connecting legs. Apart from the 6 pieces of angle being welded to the main side profiles, the rest is a bolted assembly.

I have set non penetrations to all the tubes and connecting legs. i have fixed on the 4 off faces on the base and applied a load to top hanging channel profile. The aim of this was to simulate a pull test. I have tried to apply restraints and ran the simulation but parts keep disappearing onto the other side of the work space and when they don't i can't see any loads paths on the final result as if nothing has happened.

I'm just struggling to realize which restraint is best used in which circumstance and My question is how do i restrain this properly to give the best real life simulation results?

Thanks in advance for any assistance, much appreciated for any help.
