Improperly Connected Idealizations
These problems are often caused by idealizations that are not connected to the rest of the model or not connected to adjacent idealizations.
• Beams are connected when they share common endpoints. Shells are connected when they share a common edge and the endpoints of that edge. Solids are connected when they share a common face and the edges and endpoints of that face.
• Beams are best connected to shells when the beam and shell share a common edge and the endpoints of that edge. Shells are best connected to solids when the shell and solid share a common face and the edges and endpoints of that face.
• Two adjacent shells that share two points but no common edge can cause an error.
