Hello,
I have updated the software from the 14 to the 2017.1 version and when I am trying to select the 2D elements to add to the BSURF group in order to define contact in a BCTSET card in NX Nastran user profile, no elements are selected. Is this a bug of the software or has there been a change in the way to specify contact of which I am not aware of?
Thanks in advance.
