Warning about Temperature??

May 15, 2002, 09:57

Hi, all. I found the warnings about temperature by viewing .info file. But I can't understand why they appear in my .info file.

The file is following... ----------------------------------------------- WARNING#1. Temperature less than min. range temp. at 147 cells. Minimum temp. of .100E-24 at cell 4001. WARNING#2. Temperature less than min. range temp. at 148 cells. Minimum temp. of .100E-24 at cell 4001. WARNING#3. Temperature less than min. range temp. at 149 cells. Minimum temp. of .100E-24 at cell 4001. WARNING#4. Temperature less than min. range temp. at 150 cells. Minimum temp. of .100E-24 at cell 4001.
:
: (they appear after every iteration) ----------------------------------------------- Cell 4001 is one of my inlet boundary cells. Its initial and boundary temp. are 300K. I can't understand the mean of the above and hope someone may tell me why. Thank you.

Have ypu check the velocity component at that location? It might be the sudden change of velocity. also could u explain ur case more detail?
