In the attached example, there is a load of 100 on the edges of one side of the "Y"-shaped shell, and a boundary condition of 0 set on the other side of the "Y". The shell is set to have a thickness of 1E-9. When I try to run this, I get many "face X is not valid for element Y" errors, and all the problematic elements seem to be connected to the load edges. When I try two BCs instead of one load and one BC, then just get a non-descript error:
"Job test9: Analysis Input File Processor aborted due to errors.
Error in job test9: Analysis Input File Processor exited with an error.
Job test9 aborted due to errors."
An excerpt from the .log file for the first case:
"Run pre.exe
!!! EXCEPTION:
!!! Attempt to create a cset with duplicate entries."
...
"*** Error: ABAQUS/pre exited with error 1785
*** ERROR CATEGORY: PRE"
Any thoughts would be appreciated. Thank you!
