Issue regarding creation of Partition file
 
Hi,

I am facing an issue while creating partition file and it is in the form , as cited below:

| ERROR #002100011 has occurred in subroutine cVolSec. |
| Message: |
| A negative SECTOR volume has been detected. Execution will proceed |
| but this is a possible cause of robustness problems. |
| The location of the first negative volume is reported below. |
| Volume : -0.5023E-12 |
| Location : ( 0.16063E+00, 0.14575E+00, -0.13637E+00) |
| This warning may be made fatal by setting the expert parameter |
| 'negative volume option = 1'. |

| ERROR #002100012 has occurred in subroutine cVolSec. |
| Message: |

| negative volume is reported below. |
| Volume : -0.5306E-11 |
| Location : ( 0.31089E+00, 0.28364E+00, -0.50454E-01) |

While creating Metis type partition I used 72 processors under PVM Distributed parallel.
Checked each domain separately ,there is no such error produced as mentioned in the file.
Mesh size is 37.4 million.
I use 16GB RAM m/c.


'negative volume option = 1'- If such option can be used for multi domain ,please let me know.

Please suggest.

Regards,
Jwala.
