Parallel processing warning
 
Hi there,
I am trying to run my case in high performance machine with 120 processors.

the same case is running in machine without any problem with 4 processors.
I am using MRFSimpleFoam,

While running the case in HPC with 120 processor I am getting the error as follows:

No field sources present

--> FOAM Warning :
From function MRFZones(const fvMesh&)
in file cfdTools/general/MRF/MRFZones.C at line 65
The MRFZones are not run time modifiable
using 'timeStampMaster' or 'inotifyMaster'
for the entry fileModificationChecking
in the etc/controlDict.
Use 'timeStamp' instead.


after this warning the calculation is going on.

Do I need to worry about it? can anybody give me some idea??

Thanks for your time and help,
Aadhavan

Hi,
I didnt notice any problem in the results, however you can fix that warning message following the given instruction in the warning message.

The MRFZones are not run time modifiable
using 'timeStampMaster' or 'inotifyMaster'
for the entry fileModificationChecking
in the etc/controlDict. // this is the file one you need to edit
Use 'timeStamp' instead.

Thanks,
Aadhavan
