Hi everyone,

I am using a LES model to do one transient simulation for one square pipe, but in the *.info file I found there are the following messages:

MAXIMUM COURANT NUMBER = 2.092E+00 AT CELL 54851 MEAN COURANT NUMBER = 2.594E-01

*** WARNING #038 *** UNNORMALISED RESIDUAL CANNOT BE REDUCED TO 1.000000E-10 IN EQ: PCOR

ROUND-OFF ERROR RESCUE NOT ATTEMPTED; SOLUTION RETURNED WITHOUT UPDATE

Any ideas to avoid these warnings and problems: the solution returned without updata?

Thank you very much for your help!

Lee
