I am performing frequency response on a large model. For a set of grid points, I want the response of every grid point due to unit forcing at each grid point dof. In the past, I have set up DLOAD cases for each unit force, but I then discovered that FRF does that exact thing. Recently, with a new model, I am getting a FATAL error when I use FRF that does not happen for the identical DLOAD case.
Specifically, if I run FRF with
FRFXIT1,3,115910
the .f06 file gives an unspecified FATAL ERROR and says
*** SYSTEM INFORMATION MESSAGE 1156 (XCLNUP)
GINO FILE 101 WAS LEFT OPEN AT PROGRAM TERMINATION.
*** SYSTEM INFORMATION MESSAGE 1156 (XCLNUP)
GINO FILE 121 WAS LEFT OPEN AT PROGRAM TERMINATION.
*** SYSTEM INFORMATION MESSAGE 1156 (XCLNUP)
GINO FILE 120 WAS LEFT OPEN AT PROGRAM TERMINATION.
*** SYSTEM INFORMATION MESSAGE 1156 (XCLNUP)
GINO FILE 118 WAS LEFT OPEN AT PROGRAM TERMINATION.
The .log file says
16:58:53 NSEXIT: EXIT(20)
16:58:53 Analysis complete -20
However if I run with
DLOAD 200 1.0 1.0 141
RLOAD1 141 151 6
DAREA 151 115910 3 1.0
TABLED1 6
0.0 1.0 100.0 1.0 ENDT
there is no problem. I would like to understand this error and how to fix it.
