I'm trying to fix the flange that i am applying a force to, but if i fix the flange it wont move but if i leave it unfixed the flange folds over like this in the simulation...any suggestions...?
what does the model look like undeformed?
seems like the flange is not as stiff so it is bending first
why not put a stiff plate on it and then push down?
I've tried that with a metal ring and somehow the flange still folds. I'm just trying to display it having axial movement and or compression. At the moment I'm just trying to display it compressing properly, sort of like an accordion so to speak.
Best to post the model.
Here is the attached part

I didn't see the metal flange in the file you attached?
Also, I did not see a simulation set up?
Are you using Simulation Xpress or are you using SolidWorks Simulation?
I've tried with both, granted I'm not too educated with Sim but have just been slowly hacking away on it....
still no simulation study in that one.
is there a reason why the bellows are filled with material? that is going to make things pretty hard to compress.

I would expect a strong foundation in basic modeling before beginning to tackle a complex topic like FEA.
I noticed that your sketch is not fully constrained making use of symmetry about the origin. (axis 1 is not really needed)
I noticed a bunch of repeated dimensions. I would use Equal (=) relations rather than repeating dimensions.
Analysis implies that editing might be done based on the results. It is much easier to edit a simply and fully constrained sketch without duplicated dimensions.
I noticed that the material is not uniform thickness - how will this be manufactured, I would expect uniform thickness or thinning in this area, not thickening?
I would think the model you attached is in it's compressed form already, not in it's extended form?
And it would certainly be easier to see what you have already attempted if you attached file that has your analysis attempt included.
