Contact Set Problem

Ray Cardenas Aug 8, 2013 5:22 PM

Hello,

I’ve run into a problem with the analysis of this part, which is still under construction. For some reason, and this has happened on other parts, when I try putting a Contact Set/No Penetration/with a coefficient of friction between the bottom of the Window and the top of the Peek Washer, I get this Pop Up about large displacements. Whether I hit Yes or NO the analysis fails, however if I don’t put the contact set in place the analysis runs. Can someone tell me what the problem is? or if I'm doing something here incorrectly please. Please refer to the enclosed files to see the assy & pop up window in question.

Thanks,

Ray

assuming here that your global contact is bonded.

if so, it means most likely your problem is unrestrained. when bonded, the assembly is held together. without it, your problem is unstable. use soft springs to confirm this.

if you're able to add a bit of stability to the problem and your parts are deforming a lot, you can try the large deflection option for static. if that works or potentially doesn't work. you may need nonlinear.
