TCFD® Scaling Benchmark



One of the most important features of any CFD code is its scalability. In other words, in modern CFD, it is critical for any CFD code to show a linear speedup with increasing number of simulation cores.

Francis Turbine TCFD code
Recently, we made a detailed study on TCFD® parallel scaling. The tested case was a Francis hydro turbine. The scaling results are amazing. Here are the key figures.

The detailed pdf paper of the full study is available on request.

This study clearly proves that TCFD® has very high parallel scaling efficiency. For this reason, TCFD® users can fully benefit from the fact that TCFD® can be run on an unlimited number of processors (cores).

As you know, the TCFD® numerical solver is based on OpenFOAM®. This means that this study also proves that also standard OpenFOAM® has very high parallel scaling efficiency.
