Technical specification

zCFD from Zenotech is a new computational fluid dynamics (CFD) solver designed to make simulation at scale fast and affordable. zCFD runs efficiently on modern many-core computer hardware and can convert unstructured meshes from most commonly available formats.

zCFD is fully parallel and can simulate turbulent flow (RANS, URANS, DDES or LES) including automatic scalable wall functions. zCFD is a fully compressible solver, with preconditioning for low Mach numbers and can be run in either standard finite volume mode or with new high order (DG flux reconstruction) capability for efficient scale-resolution.

zCFD has solution acceleration via geometric multigrid, dual-time-stepping and polynomial multigrid. zCFD will automatically detect and run on NVidia GPU accelerators where present.
