1. Create a nanotube.
2. Add a simulator with the Brenner Interaction Model (no need to run it).
3. Delete the Structural Model with the nanotube.
This leads to an immense growth of the used memory and freezing of SAMSON. The bigger the nanotube the bigger the later growth in memory. If the system with nanotube[s] is quite big then it leads to the usage of a virtual memory and SAMSON will take ages to unfreeze.
