Re: Part sag under its own weight
In "big boy" FEA, this is done by applying acceleration equal to gravity. SW's Express does not allow this.
If your part is uniform enough, you could approximate with a directional load distributed across upward-facing surfaces.

Re: Part sag under its own weight
I tried this at first, but the part was deforming so widely, that I thought there must be an error.
I will give it a second look. Thank you for your help.

Re: Part sag under its own weight
You're stuck with forcs and pressures in simxpress. Roland's workaround might work. Might want to apply it along the center/cog.
If you need this analysis run for you, we provide that service at hawk ridge systems. Just email me at jared@hawkridgesys.com.

Re: Part sag under its own weight
Thank you for your suggestion. I will contact you if I go nowhere with the simxpress simulation.

Re: Part sag under its own weight
Just wanted to give some update : I used the simulation premium package to simulate my part (my institution has a few licenses you can borrow). I am glad I did : the sag is so terrible I don't even want to belive it is !
So now I am off to change my design and manufacture my part in a different way ;-)
