Within Materials Science and Engineering (MS&E), there exist semi-segregated programs; ceramists infrequently interact with metallurgists and both of those communities rarely interact with polymer scientists. In terms of Computational Materials Science and Engineering (CMSE), the underpinning theories, algorithms and computing protocols evolved independently to address science questions and engineering needs for their own communities. Each discipline brings different perspectives and computational strategies, which are bound to have value for the other sub-disciplines. The purpose of this GRC is to see what we can learn from one another by comparing and contrasting development of theory, algorithms and best practices across sub-disciplines of MS&E.
