In version 2024.f a new operation is implemented to add stiffeners between a plate and a circular hollow section. The stiffeners are arranged around the circular hollow section radially and parallel to the section axis.
As well as the geometry of the stiffeners, users can define the number of these plates, which will be evenly distributed from an initial angle, around the user-defined angle. The point of origin of the initial angle coincides with the y-axis of the section.
