AB  - This paper discusses in-situ visualization in the context of high-order GPU-based CFD solvers. For this purpose, ASCENT was coupled with NekRS and successfully used on JUWELS Booster and Frontier to visualize CFD applications, a Rayleigh-Bénard convection case and a Pebble Bed reactor, at scale. The setup allowed time-resolved visualization at low additional computational cost.
