I suspect I am missing something simple, but I would much appreciate your advice.
I am calculating buckling in a sandwich structure. The shape is a so-called stellated icosahedron. I calculate for different values of a certain integer parameter n related to the number of edges. I am having no problems with n=1 and n=2, but for n=3 I start getting errors, such as
*ERROR reading *ORIENTATION: distribution
-4.265755714032843E-5
has not been defined
The relevant lines in the input:
*MATERIAL,NAME=C39
*ELASTIC,TYPE=ENGINEERING CONSTANTS
6.6879e8,66.879,66.879,1.0e-5,1.0e-5,1.0e-5,1.379e8,1.379e8

*ORIENTATION,NAME=OR39

*ELSET,ELSET=ELC39k4,GENERATE
664702,665124
*SOLID SECTION,ELSET=ELC39k4,MATERIAL=C39,ORIENTATION=OR39
Why is the number read as a name of a distribution?
Another (apparently, induced) error:
*ERROR reading *SOLID SECTION. Card image:
*SOLIDSECTION,ELSET=ELC39K4,MATERIAL=C39,ORIENTATION=OR39
*ERROR reading *SOLID SECTION: nonexistent orientation
The relevant lines of input are the same.
The ccx input file is temporarily at akhmeteli.org/newbuildorder.zip , but the zipped file is very large (about 100 MB).
Another thing I don’t understand. When I click on the ccx input file, I get numerous messages:
ERROR in seta: A negative entity-index:-1 was used in set +dlo
I use a Linux ccx_2.19_MT executable from feacluster.com.
Thank you
