Warning 052

July 5, 2007, 16:13

I am a relatively new STAR user and Im currently modeling some creeping flow. I am recieving the following warning:

*** Warning 052: Residuals in eq. UMOM have reached

round-off error limit 1.000e-11 in iteration 1

If you suspect that this limit is too high, set the real

constant c30 to a lower value.

I get the same error for the v and w momentum as well. Does anyone know how to change that value (c30)? Thanks in advance.

Found it. Hope this fixes my problem!

There isn't anything to worry about with that error anyway, it just means your residuals have dropped below the default round off limit
