Hi all
I have this sliding box, when I look in the cvg-file the number of contact elements vary from 46 to 208. When I extract all contact nodes from the cel-file I only get the expected 14 active nodes. It seems like contact nodes are counted randomly more than once.
If anyone should have a plausible explanation for this, then please share.
