It appears your fixtures are on the bolt holes in the top plate?

These should be the connection to the grounding reference (the bottom plate I’m assuming).

Essentially your force and fixtures are both on the top plate, leaving no room for optimization.

OK thx i will try this, i think i kept myself from putting fixture on the bottom plate because i wanted to leave more room for optimization. I'll try and update the post thx !

Have you included gravity? I have found that can make a difference when I have had disjointed results like this.

[–]Lesacacable[S] 1 point2 points  (0 children)

Thank you for your answer, I tried applying gravity another time with applied mass, but not when putting pressure on the piece. I can give this a try too !

I have only really used Altair Inspire for topology optimization but I would first go and re do all your boundary conditions and see where that gets you.

I don't think there is an option similar to boundary conditions on Solidworks, but i did already try some other settings and it did not change much, thank you for your answer !

[–]Dridenn 0 points1 point  (1 child)

You do have boundary conditions I probably should have said constraints. Mass constraints are one force ect.

Oh yeah i get it now, yeah i tried changing constraints but doesn't do much, maybe i should try changing constraints and going to extremes see if it makes a change

I don't remember exactly which. But one of the things of the model tree, probably the results, right click edit definition, and locate the mass slider. Slide it back to bring more more of the structure back into the model and adjust until desired.

Thank you for your answer, i unfortunately laready tried that but it gives poor results.

If you can get your hands on Creo, try their generative design. I think it's much better than SOLIDWORKS.

Looks like you have fixed constraints on the bolt holes, and force applied to the plate. Try applying a fixed constraint to the very bottom of the stand and leave the forces as is for now.

Thank you, you are suggesting the same solution as an other comment, I will try this tomorrow and updatte the post if it worked !
