Program draft
Program
Mostly, general HPC/CFD topics are covered.
Particularly, during the afternoon session, we also address machine-specific aspects of Lise/Berlin & Emmy/Göttingen.
Morning session “Build your own solver”
=============================================
09:30 Welcome
[Lewin Stein - Zuse Institute Berlin]
(attendees background check: how many years of experience working with:
- StarCCM, OpenFOAM, Paraview, Ansys, Abaqus or own-CFD-code?
- Fortran, C/C++, Python/Julia/Jupyter, Matlab?)
09:40 10:00 Start & welcome
10:15 CFD project planning on a supercomputer
[Lewin Stein - NHR @ Zuse Institute Berlin]("start small", data management, numerical precision)
10:30 Basic libraries 40 Basics of parallel computing: SIMD, OpenMP, MPI, parallel I/O
[Matthias Läuter - NHR @ Zuse Institute Berlin](when and how to use on our system, future challenges: accelerators)
11:30 CFD parallelization 12:10 CFD Parallelization concepts, scaling tests
[Lewin Stein - NHR @ Zuse Institute Berlin](structured single/multi block, space-filling curve for unstructured grids, strong/weak scaling, literature recommendations)12:00 Parallelization of the CODA CFD Solver
[Michael Wagner - German Aerospace Center
DLR]13:00 Lunch break
Afternoon session “Use of CFD software”
=============================================
14:00 StarCCM, Parallelization of the CODA CFD Solver
[Michael Wagner - German Aerospace Center Dresden DLR]
14:30 OpenFOAM, Paraview
[Jack Ogaja - IT centre Göttingen University GWDG]
(basic use, PoD key retrieval, OpenFOAM versions & advices on metadata I/O, pvserver, ...)15:30 Ansys, Abaqus, VNC Viewer NHR @ GWDG, Georg August University of Göttingen]
16:10 Ansys, Abaqus, comment on GUIs, feedback session
[Lewin Stein - NHR @ Zuse Institute Berlin]
(basic use, license issues)At the end: Feedback questionnaire
(Which topics would interest you in more detail at the next CFD day?)
17:00 End
