Hi guys,
I'm working on Calculating the difference between inlet pressure and out pressure. I have a problem, my result from auto timescale and physical timescale is not same. Early, I think it is a result from the convergence of the simulation because physical timescale got RMS better. But when i change physical timescale to make RMS same auto timescale case, Pressure is similar to before. I don't understand why. Follow my searches, physical timescale just provide sufficient relaxation of the equation and not affect the result. It means the results is not different.
Has Anyone even work on the physical timescale can explain ?
Thanks a lot

This is discussed on the thread I posted on this morning: Minimum mass and momentum RMS residual levels

The different time scales results in different machine precisions, so the final convergence level is a bit different.

But hopefully the actual results between these simulations is essentially identical.
