Problem in running STAR-CD Case in multiple processors
 

Hi,
I am running a case in STAR-CD. The case runs fine in 1 processor. However, when i execute it in 2 or more processors, i am getting the error:

Error encountered, number: 76

*** Error 076: Negative densities found at more than 100
cells.

RUN STOPPED !!!

PNP: Shutdown [2014-05-06-15:46:48] Execution terminated after 82 seconds (OVERALL ELAPSED TIME).
[s126787@node021 Case_750K_15O2_Inj_Pr_6MPa_sr200_parallel]$


Then i checked the .info file. I found the following warning:

*** Warning 056: In domain 1 one of the following values
for initialisation is too small: k or epsilon for KEPS
option or turbulent intensity or mixing length for MIXL
option. Initialisation method is now MIXL with turbulent
intensity 2.582E-02 and mixing length 1.000E-01.


Any suggestions to solve this problem?
