Computing is central to the advancement of modern science. These stories illustrate ways in which software in the CASS ecosystem is used by other computational scientists, or even other organizations, to facilitate advances in their fundamental research, as well as advances in computer science and applied math embodied in the software products themselves.

Magnetically confined fusion plasmas are being designed within the International Tokamak Experimental Reactor (ITER) and other projects that are based on physics regimes achieved through present experiment. First-principles-based modeling and simulation activities are required to design and optimize these new facilities in the possibly new physics regimes. The fusion community...

WarpX is a particle-in-cell (PIC) simulation code that models the motion of charged particles or plasma. WarpX is used to model chains of plasma-based particle accelerators for future high-energy physics colliders – table-top particle accelerators. These table-top accelerators can be used in both scientific and medical applications.
