The temperature and velocity distribution shape are the same, only I got slightly higher temperature in lower convergence criteria. So do you have any comments on this. I can converge while still...

Now my convergence criteria is 1e-06, so your suggestion is getting to 1e-05 and see the result? I have done the grid independent study, the mesh is ok. And from the help file, it says"When you are...

WHile from the attached graph, I do not have poor grid quality, so what kind of...

During the running, I found RMS of U,V,W-Mom and H-energy is one order higher than MAX, for example rms=2.5e-06 and max is 1.4e-04, how...

From the original sentence, "it's often necessary to alter the physical timescale", so I do not need to use a CEL language to alter it from time to time? just use a fixed number for example 1s?

Replies: 10 Expression for physical timescale Views: 2,699 Posted By xyq102296 Expression for physical timescale From the help file under physical time scale chapter, "It is often necessary to alter the physical time scale for buoyancy driven flows in order to achieve convergence." So max physical time...
