insert fictitious elements for structural checks

[Ing.Vedder]

Hello everyone,
I am impracticing with inventor 2010 to make some very simple fem verification.
I would like to know if there is a possibility of inserting into the part that I want to analyze rigid parts like fictitious beams to simulate links, constraints or anything else.
For example, you think I want to simulate a locked cylinder in place, I thought I would simulate it as an infinitely rigid beam stuck in the position I need.

I hope I explained. understandably. .

thanks to all

I don't think I understand the problem well, but I don't think so. probably you can solve using the constraints or contacts, in your example I would put a glued contact between the piston and the cylinder so that it makes them monolithic

hello diegus and thank you,
I tried to explain better with this sketch. I hope you understand something more...
I know that this can certainly be done on ansys.
in practice consists in simulating unmodeled parts (because of difficult modeling and to which we may not be interested) using fictitious elements.

I sketch here, thank you all

a small up...
I am also ready to hear alternative ideas on how to do structural verification that I have made you an example!

Thank you!

if the cylinder is fixed then replace it with a pin bond in the upper eyelet. the presence of the trolleys makes me think that the "sedia" should slip on the tilted plane, here you should put some sliding constraints between the sloped plane and the edge. If so the result does not satisfy you use the dynamic simulation environment, design the chair with the rails, you also put the cylinder joint with its resistance and then expose the binding reactions to make the test only on the chair.
