Hi,

I finally get my simulation correct. The solution found to be i was using a wrong geometry >.< After modify it to a proper one, i get my results very close to experimental one. ;)

Stuck again

Hi aqstax,

How are u lately? hope u are doing fine there. I get stuck again in my simulation. I now stuck in results extracting. Mind share me how u actually get torque value from periodic domain...

Thanks for the reply. So the tet-unstructured work good for you. I shall try on the tet-unstructured as well as hex-structured mesh then. Have a nice day.

Regards,
Lacer

Hi aqstax,

I am doing a similar type of simulation on CFX. I was encountered the same problem ( simulation torque value is half of expected torque value ). My simulation case is tidal turbine...
