摘要

•Development of a 3D cut cell algorithm, state redistribution (SRD), for finite volume methods on engineering geometries.•Generalization of the original SRD approach that is less dissipative at the embedded boundary and smoothly activates.•SRD is extended to PDEs with reaction and diffusion terms in both compressible and incompressible flows.•SRD has been included in the open-source exascale framework AMReX, which runs in parallel on hybrid CPU/GPU architectures.
