Hi, I want to convert abaqus deck with contacts to nastran deck.

Currently I have 2 methods only.

one is to use hypermesh to convert abaqus to nastran. But this method doesn't convert contacts.

other is described in this video https://www.youtube.com/watch?v=c_rfMPpnUPo
which uses a nastran utility to convert. it does convert contacts but it also misses some contact option.

Do you guys know any better option for conversion.
