*** SYSTEM INFORMATION MESSAGE 1156 (XCLNUP)

GINO FILE 107 WAS LEFT OPEN AT PROGRAM TERMINATION.

Previously I ran similar Jobs with large number of Loadcases. Now I need to reduce the number of Loadcases because of this on Nastran2013r1. Why is adding ALTER the solution? Or is there any other alternative to run with all loadcases?

There was an issue in v2013 where a very large SET could result in this error. Do you have a data request referencing a large SET? If so, try using ALL instead and see if that helps.

This might be related to having a large number of CWELDS- do you have a lot of CWELDS? If so, the ALTER below can help but eliminates the CWELD results from data recovery.

$ Nastran 2013r1 sol 101 alter to delete all MODUG references in subdmap sedisp

compile sedisp nolist $

alter 308,309 $

alter 606,607 $

alter 687,688 $

The best thing might be to try a newer version of Nastran. Even the next release, v2014, should avoid this error if the root cause is either of the previously mentioned items.

Hi Don.Graff,

I used the above ALTER and it worked, and I dont have CWELDS. There are many CFASTs. But we keep solving the same size problem differently, and this is the first model I encountered such error.

Yes the SET is large, I will give you feedback if it works with ALL.
