converting contacts in abaqus to nastran

[kammieorama]

Dear All,

I am trying to convert a few abaqus files having contacts to Nastran files.

I am using medina for this conversion.

The contacts are coming as BSURFS element.

Now i have a few questions.
1. Is this the right conversion ? is contacts and BSURFS are they equivalent

2. what is the way to define contact pairs in Nastran.?

3. will these pairs give the same result as abaqus?

4. should i define surface in the case controll section

thank you in advance
