Hi, I am looking at using the SST Curvature Correction in a flow simulation and am struggling to figure out how to use it! I have enabled the beta features, and now can not find where the curvature correction option is, would someone be able to give me some explanation of how to use it or point me in the direction of a tutorial? Cheers Mike

Hello Mike,

In CFX-11 go to Fluid Models in Domain definition. Then Turbulence Model - Shear Stress Transport, Advanced Control - SST Curvature Correction - on.

hi hdj, As you suggestion, But I can't find the SST Curvature Correction all the same. In the CFX help, there have the option of SST Curvature Correction and SST Reattachment Modification. but i can't find in the CFX-pre, I don't know why? Regards

You should export *.def file to *.ccl and modify it. There is no GUI for this option.

would someone be able to correct this for me as I dont know how to edit the ccl files!

FLUID MODELS:

COMBUSTION MODEL:

Option = None

END

HEAT TRANSFER MODEL:

Option = None

END

THERMAL RADIATION MODEL:

Option = None

END

TURBULENCE MODEL:

Option = SST

TRANSITIONAL TURBULENCE:

Option = Fully Turbulent

END

END

TURBULENT WALL FUNCTIONS:

Option = Automatic

END

END

Thanks Mike

Hello Wei Chen,

First of all check out whether beta features are enabled. (Edit - Options - CFX-Pre - Physic Preferences - Enable Beta Features)

Hi, I have the beta features enabled, but as there is no GUI for editing the curvature correction could someone tell me what i need to type into the command editor and where to turn the sst curvature correction on? Cheers Mike

Hello Wei Chen, Hello Mike.

Strange that you don't have a GUI for it, anyway here is that section in ccl:

TURBULENCE MODEL:

Option = SST

SST Curvature Correction = On

END

Regards

CFX is a commercial package and the source code is not available. You will have to look at the references to academic articles listed in the documentation.
