Xolotl

Xolotl is a continuum simulator under development within two DOE SciDAC programs, available at https://github.com/ORNL-Fusion/xolotl . It is a high-performance computing code using advection-reaction-diffusion (ADR) kinetic rate theory to model the time evolution of the divertor material in next generation tokamaks like ITER, as well as nuclear fuel in fission reactors.
