BioDynaMo is a versatile, open-source simulation platform designed for modeling complex biological systems (https://www.biodynamo.org). It offers a flexible framework for building and simulating agent-based models, enabling researchers to explore a wide range of biological phenomena. Here, we will give an introduction into BioDynaMo and explain how the principles of agent-based modelling are supported. To this end, we will present several use cases to showcase the software capabilities. Afterwards, the team will run a hands-on tutorial session where a simple simulation is conducted. The course will conclude with an interactive conversation to address FAQs and any questions raised by the audience.
