pyFBS is a Python package for frequency-based substructuring, transfer path analysis, and also, as new additions, multi-reference modal identification and a variety of different expansion techniques. It enables the user to use state-of-the-art dynamic substructuring methodologies in an intuitive manner. With the package also basic and application examples are provided, together with real datasets, so you can directly try out the capabilities of the pyFBS. It is not only currently being used by several undergraduate students and postgraduate researchers but also offers great potential in various industrial projects. Within this chapter, a short recap of pyFBS capabilities is presented, and plans for the future goals are set. The pyFBS team plans to share the most advanced tools and methods in the field of dynamic substructuring and transfer path analysis. The goal is to create a common working base for scientists interested in this topic.
