Transition Interface Sampling (TIS) and Partial Path TIS are two methods for the simulation of rare events, transitions between stable states separated by a high energy barrier. They were devised by Dr. T. van Erp and developed by van Erp and myself under the supervision of Dr. P. Bolhuis.

I applied the methods to study the case of a supercooled liquid, where solidification is not initiated until clusters of a critical size are formed. I make available here the simulation code I developed. For all the theoretical details refer to my PhD thesis.
