Hi Both,
The balance I am implying here is less to do with accuracy of the results and more to do with practicality. Doing CFD in a practical sense is always about this balance and thats where I’m approaching it from. If I sacrifice some result accuracy but get a result in 1/3 of the expected run time, thats an approach that I will likely take.
Of course the other end of the spectrum is also depending on how sensitive your results are. If say the result of a 1% to 2% difference adversely affects your problem, then you have to exchange time for accuracy instead.
All in all, this doesnt mean that the investigation into how the relax factors affect results should stop, instead I think the work both of you are doing is fantastic and do keep on going. Its been very insightful to read through the data and form some conclusions and assumptions.
Cheers.
Regards,
Barry
