This high-resolution simulation of two-fluid mixing in a spherical geometry was run to gain insight into the growth of Rayleigh-Taylor instabilities important for inertial confinement fusion (ICF) simulations. High resolution simulations of instability growth are not practical for routine use. Simulations like these help to guide the development of sub-grid models with less computational cost.
