Performance of OpenFOAM

Wandadars · June 13, 2016, 13:13

I can't seem to find any posts here about the topic of the performance of OpenFOAM. The V&V forum seems like the best place to include information about the performance of OpenFOAM. Does anyone know of any scaling studies that have been done using OpenFOAM to see how scalable the software is? I'm interesting in finding data on how large of a problem the code was successfully run on e.g. something like 500 million cells on 60,000 cores.

I tried contacting the OpenFOAM foundation to ask them, but I haven't heard anything back yet from them about the scalability of the code.

Did you search google scholar?

Thank you! I tried just regular Google searches, but I forgot about Google scholar.

there is a SIG HPC

testcases from the SIG turbomachinery are quite big
