Agent-based simulations are increasingly popular in exploring and understanding cellular systems.
Molecular models are computationally demanding but are crucial to study key cellular phenomena such as molecular crowding.
The proposed agent-based approaches contribute to high performance three-dimensional molecular simulation.
Our approaches may be implemented in typical Life Sciences research centres and do not require specialised computing skills.
Our approaches may be applied to any model at molecular level and have the potential of being used in any agent-based tool.
