Pecube is 3D thermal model that tracks exhumed sample cooling histories and calculated predicted cooling ages. It also allows for the simulation of topographic evolution and is (optionally) coupled with the CASCADE surface process model.
The following web pages are available for available as documentation on the program.

Python program for creating velocity input files for Pecube from 2DMove (07.11)
This explains how to run several pecube simulations sequentially on the ESD Cluster
