Hi,
I am really new at that nonlinear simulations and I am having some issue with making a press plate move down on to my part. My project is taking a lid to a cup and applying it to a cup using a press plate (similar to a top down compression test). I currently have it cut in half, so I can have a higher mesh, because of this I have semmetry on all the 3 of the part in the assembly. When I have my mesh on draft quality, my displacement on the press plate would push the lid down and on to the cup, However, when I changed my mesh from draft quality to normal mesh quality the displacement on my press plate goes from moving 17 mm plus to moving 1.2 mm. This is the video I have with draft quality mesh lid application https://www.youtube.com/watch?v=8NxoawqFrPw&feature=youtu.be
Here are my current setting, fixtures, and warning that I have on my parts.
On Flate Faces -2 Translations: x-0mm, y--15mm, z-0mm
On Flate Faces - 3 Translations: x-0mm, z-0mm
On Flate Face - 4 Translations: x- 0mm, y-0mm, z- 0mm
The warning I get when I am running the simulation is Max. allowable iteration increased by 5, and PCDLSSO102: Assembled Stiffness.
Can I get some help with why my displacement changes and does not push my press plate into my lid in the non-draft quality mesh.
Thank you.
Hi Megan,
Can you simplify things down a bit more by making sure the lid and the press and the cup are all initially touching. It makes it harder to converge when things aren't initially touching. Take a look at this video at 3:30 to see how you can make the bodies initially touching.
Looking at your geometry, you'll probably want to go with option #2 like Shaun said. The ruffles on the lid will prevent you from option 3.
All the best,
