Objectives:
During this course the metodology of Computer Aided Material Design (CAMD) will be presented. It will be shown how to use the computer to virtually "produce" new materials and investigate their properties. Despite of providing practical skills in materials simulations, the laboratory classes will provide a good opportunity to focus also on the computer science aspects (computer architectures, data operating systems, parallelization, time-sharing, optimisation, etc).
