How to slove "temperature limited to 1.0000e+00001 in cells.."

Posted November 22, 2012 at 12:11 by diamondx

This might happen early in your solution, but it should go away as you iterate. What happens is that FLUENT calculates some value that is below 10 K, which is (probably) unreasonable. To keep the simulation from diverging, it discards the value it calculated and uses 10 K insead.

If the warning does not go away as you iterate, try to find where the offeding cell is. You can do this by going to the adapt by iso-value menu and selecting adapt by temperature. Pick a range of temperatures...

All Quad

Posted November 20, 2012 at 17:05 by diamondx

So if you want to use swept, change the "free face mesh type" to "all quad". Then the sweep will turn those quads into all hexa...

Otherwise, perhaps you should be looking into the regular (not swept) blocking.

Average static Pressure and uniform static pressure

Posted November 8, 2012 at 05:52 by Far

What is the physical significance of both options. When to use static pressure (fixed every where) and when to use the Average static pressure(floating with average constrained)?

In my opinion static pressure condition may be the good for the boundary far away from the object to be studied, in other words flow is more or less uniform at outlet boundary.
On the other hand the average static pressure may be more physically correct as it allows the conditions to vary along the...
