3D contact- unconverged solution one or more elements highly distorted
3D contact- unconverged solution one or more elements highly distorted
(OP)
Hi,
I am trying to model a situation where load being applied to a flat surface through a soft rubber like loading patch(curved surface).I was using displacement control for contact analysis and tried many things so far with no luck.
Here is the problem description for you all:
h ttp://www. geocities. com/online user2006/e lementshap eerror.ppt
good elements plot(http:// www.geocit ies.com/on lineuser20 06/element s-good.jpg) and (distorted element plot(http://w ww.geociti es.com/onl ineuser200 6/error-el ements.jpg). Se annimation before unconverged substep(htt p://www.ge ocities.co m/onlineus er2006/bef ore-unconv erged-anim ation2.avi) and at unconverged substep(http://w ww.geociti es.com/onl ineuser200 6/error-el ement-anim ation1.avi).
If I apply displacement more than 0.5inch, I get the error that "one or more elements are highly distorted ..". But in actual lab test I applied up to 1.75 inches without any problem. So, at least I like to apply 1-1.25 inch. Right now I am trying applying 1 inch in te example shown. But the error comes up.
Does anyone give some advice on how to resolve the issue? I will greatly appreciate if you kindly advice me on this.
Thanks.
