Error: Parameter Bounded CDS is not allowed
 

Hi Everybody,
I have problem regarding Central Difference Scheme. Somehow cfx 13.0 gives me the following error irrespective of the fact that i enable this "bounded CDS" (Under solver control/Basic Settings/ Advection Scheme) or not.

Error: Parameter 'Bounded CDS' is not allowed in /FLOW:Flow Analysis 1/SOLVER CONTROL/ADVECTION SCHEME

Actually i want to do LES simulation of fan. I have found out that in order to do some les simulations its recommended to use Central Differencing but somehow its not working for me. Do i need to enable something in expert parameters in order this to work? Any help/comments will be really appreciated. Thanks in advance!!!

Regards,
Atif

What turbulence model have you selected?

LES Smagorinsky

It seems no body has a clue!!!

I have figured it out.

Can you explain what you did to make it work.

Actually i was running my simulations on cluster and i needed a batch script to run my job. There i was using version 12.1 whereas i was using 13.0 while writing def. file. Since there seems to be no Bounded CDS option in 12.1 thats why it was giving me the above mentioned error.
