Answer:
Independent substructures are not connected to each other and are considered as separate substructures in the calculation. Thus, they are independent models with no effect on each other (see Image 02).We recommend editing the partial models separately as individual files. Then, it is possible to perform the stability analysis with RSBUCK.
Otherwise, the partial models must be connected to each other. It has to be considered that the structural systems of the partial models should be retained when the partial models are combined to form a complete model (see Image 03).
The "Independent Systems" function is useful when detecting partial models. It finds all independent systems and lists them as groups (see Image 04).
You can find this function under Tools → Model Check → Independent Systems.
