Effect of number cores in processor to results

NTNHAN · May 10, 2023, 05:17

Hello everyone,

I have many case simulations using REEF3D, I use three computers that have different cores in processors (6 cores, 8 cores, 16 cores). I tried to simulate the same case using both computers, the results showed that having a difference in results.

Are the results independent or dependent on the number of cores in processors?
How can I obtain the good results in my situation?

Thank you.

Hi NTNHAN,

difficult to say, I need to see your results for a better understanding of your cases.

Dear Professor

I attach my result and REEF3D input.

Respectively Professor
