Re: Removing tied surfaces

Hi,

I read in the manual some months ago said that *tie
option cannot be removed. If you have specified it
then it will be there forever. 

So, I think you can try another interaction such as
contact, then choose normal contact. Inside that
normal contact, there is an option to not separate the
nodes (which will act like a tie interaction). If you
use this one, then this type of interaction can be
removed use *model change, remove, type=contact pair

Hope it can help you,
Darwid Halim
