Parallel performance OpenFoam Vs Fluent
 

Hi,

I came across an informal article that claimed that OpenFoam has better performance on parallel machines than Fluent. I would like to get your comments on this. I understand that there are multiple dimensions to this. But I would like to get an idea of how competitive Fluent/OpenFoam is in terms of scalability, parallelization, performance etc.

Thank you
