Contact Problem

Dear Nastran users,

actually I´m developing some axy symmetric models. And in the case I have some errors like

 

NASTRAN Msg: *** FATAL ERROR: PROCESSING OF NASTRAN DATA FOR SOL 601 FAILED.
*** ADVANCED NONLINEAR EXIT CODE 0 ***
NASTRAN Msg: ^^^ USER FATAL MESSAGE
^^^ ERROR IN ADVANCED NONLINEAR MODULE 0


Total messages: 0 WARNINGS and 2 FATALS

 

This message is very vague for me on f06 file I get a litle piece of information 

 

***INPUT ERROR: Selected element edge sets are not connected.

 

In that case I unable contact and behaviour of Nastran have been changed to error related to matrix pivot(I´have been waiting for that).

 

My problem is I dont get information about this error. Please find attached my my model. the linar problem run very good.
