I am modelling a wing using mainly shell elements. I am connecting the parts using RBE2 elements at each node, but I get errors, and singularity at several nodes. I read about solving this problem either by setting AutoSPC to yes, which is not recommended, or by adjusting the parameter k6rot to 1, so that these nodes will have a stiffness, and no singularity occurs. But if the shell is connected to a CBAR element the rotation from the CBAR to the shell will not be transferred correctly, all this is using CQUAD4 elements, so I don't know how to proceed, and how to use these parameters to get a right answer.
Using CQUAD8 elements is always popping such errors, and still I don't have a way to solve it, any help please?
