Nov. 2005, I was guest in the Grupo de Quimica Teorica y Computacional, Pontificia Universidad Catolica, Santiago de Chile, thanks to Prof. Alejandro Toro Labbe’. The main purpose was a five-session Mini-Curso “Survey of Multi-scale Materials Simulation Techniques and Problems”, in conjunction with CIMAT, Centro para Investigacion Interdisciplinaria Avanzada en Ciencias de los Materiales, at the Universidad de Chile.
