(OP)
hi all, I am hyperen and I am new in PATRAN/NASTRAN.
I am running a simple linear analysis, on a not so simple winglet!

However I get the following fatal message and so no .op2 file is written:

*** USER FATAL MESSAGE 2101 (GP4)
     GRID POINT    1000905 COMPONENT  1 ILLEGALLY DEFINED IN SETS   UM   US     

I can't see whats wrong with the definition of the grid point. Any help will be appreciated!
