Actually, that's not the problem.
I want to use beam and shell elements together. I will connect them rigidly with fix joint. So there will not be a stress concentration at the connection point. But the problem is a centerline roblem between the center of the beam element and the center of the shell element. They are not in the same line as you may see the first and seventh picture above.
How should I deal with this? Should I move the shells in order to set the centers on the same line? Is this an acceptable approach?
Thanks for your reply.
