so im connecting the slab to the circular wall, so I declared an opening to the slab which is a copied geometry of the wall opening at a lower level. However, If I don't add a fixed connection to the slab the way it shows then it gives me an execution and error and also won't analyse the wall panel when running slab/shell calculations.
The goal is to connect the nodes of the cylinder with nodes of the slab located at the edge of the opening. The easiest is to define the contour of the opening and the circle that you want to extrude into a cylinder in the same way (the same center and the same number of divisions).
