Fundamental Physics Codes and Application

Distinct from large scale ASC codes, special purpose codes are used to investigate specific physical phenomena and generate fundamental physical data. For example, molecular dynamics simulations are used in particular applications to develop insight into physical phenomena as well as to compute specific material properties. Special purpose codes are also used to develop and evaluate models prior to insertion into the integrated codes. In certain cases, these tools may also be used directly to answer specific questions from customers. This involves extensive collaborations with other campaigns and other internal scientific activities.
