Reproducible and replicable CFD: it's harder than you think

Choosing an incorrect boundary condition with IBAMR resulted in spurious blockage of vortices at the outlet. Thanks to the support received in the code users' forum, this and other problems were resolved and we succeeded in replicating previous findings.

Pi-Yueh Chuang at GTC 2016


At this year's NVIDIA GPU Technology Conference, PhD student Pi-Yueh Chuang presented the work "Using AmgX to Accelerate PETSc Codes." AmgX is an NVIDIA library that provides sparse linear solvers, smoothers and preconditioners on GPU devices. Pi-Yueh presented his work to couple AmgX with our fluid-flow solver, PetIBM. This code solves the Navier-Stokes equations on Cartesian... Continue »
