Default Low Reynolds Number k-epsilon formulation CFX 10.0
Posts: n/a
Hi All,

I am trying to implement a Low Reynolds number turbulence k-epsilon formulation, in order to compare it to a solution obtained with the SST model, using CFX 10.0. However I can't find anywhere where I can choose a low Reynolds number k-epsilon formulation " only the standard k-epsilon is available.

When selecting the standard k-epsilon model it is possible under wall functions to change the y+ value that is set to 11.06 by default. By lowering the value can I then obtain a low Reynolds formulation? " Does anyone know what altering the value will mean?

Thanks in advance Regards Chris

I'm not sure but I don't think so. I'm running ANSYS CFX 10.0 I don't know if it is included.

You should know what you have. CFX-Flo is a starter package. What does your license file say? Can you perform a run and have Pre and Post opened simultaneously?

Kim-HM is on a distinguished road
CFX option not shown in GUI, it is able to use by CCL

Clik Edit in Command Editor then CCL window will open

you can see below

Option = Scable

you can use low Re-model on every turbulent model by Scable -> Default

if you want other wall funtions option, search 'turbulent wall functions' on help in CFX
