Contact output variables in Abaqus
Contact output variables in Abaqus
(OP)
Hello,
My question is about contact output variables in Abaqus and differences between them.
I need to find what part of my model is in contact, to do that I use CSTATUS(visualisation) and CPRESS(visualisation & node values) variables. I can simply vizualize this output.
The problem is with CNAREA variable, in visualisation module(scale 1:1) at the some stage of my analysis there IS NO contact between pairs, CSTATUS=0 and CPRESS=0 in my whole model, but CNAREA is not zero.
I thought that if there is no any contact CNAREA should be equal to zero too, but it isn't.
Where is the problem?
Thank You!

Yes, I have noticed that, but I was nor sure if my approach(assume this values as zero) was correct. I was a little bit suprised :)
So if I'm not wrong, in the end I assume that the true contact between this two pairs is at the brink of my cantilever.
Thank You, your post are very helpful.
