ABAQUS-large deformation problem
ABAQUS-large deformation problem
(OP)
Hello,
i'm handling the impact problem. My question is: what causes these strage distortions and how to prevent this?
1. Before impact

2. After impact

I use status variable to see the results, but I saw analysis (on YouTube, etc.) where author didn't use status variables and results were reliable (without these strange distortion).
So what is a clue to do this analysis in a proper way?
And last question. How should I understad status variable limits? For example, I entered "1" in von Mises stress (S) max value and results looks much better...
Best wishes and thanks in advence

It looks like the deactivated elements are displayed. Use the Status variable to manage that.
