  • Frequently Asked Questions (FAQs)

In the stability analysis in RSBUCK, I receive the following error message: "The model is not connected because there are independent partial models." What does it mean and what can I do about it?

Answer

Independent substructures are not connected to each other and are considered as separate substructures in the calculation. Thus, they are independent models without influencing each other (see Figure 2).

It is recommended to edit submodels separately as individual files. Then, a stability analysis with RSBUCK is possible.
Otherwise, the partial models must be connected to each other. It has to be considered here that the structural systems of the partial models should be retained when the partial models are combined to form a complete model (see Figure 3).

The function "Independent Systems" is helpful when detecting partial models. It finds all independent systems and lists them as groups (see Figure 4).
You can find this function under Tools -> Model Check -> Independent Systems.
