Hi Glenn,

I started with selecting RNG k-e model with roughness added on the wall boundary condition. Subsequently I export the CCL first and change the turbulence model to SST using Notepad and...

Hi

just to check, when i start the solver and the roughness and SST appears in the CCL does that mean roughness has indeed been added?

Hi Tom,

I managed to add roughness using SST model. I faced the same problem as you and found out that it works (solver has the roughness and SST model appeared) when you disable the auto physics...

Hi,

for the beta feature that was mentioned earlier about adding roughness using SST model, can transition model be turned on and predict as well?

Hi Glenn,

think it would be hard lay my hands on V12 and my project due in August (time is running out!) anyway. I'll see if I can get hold of the documentations. Once again, many thanks for all...

Hi,

how to I relate the equivalent sand roughness height to the Transition roughness height (which can be found under the transition model)?

Hi Timon,

thanks for providing further insights. I am actually an undergrad working on my final year project and this is the first time I am being exposed to CFD. Since it is a beta feature, I am...

Hi Timon,

I found the beta features! Many many thanks for your help. Will try out the roughness feature.

Hi Timon,

which means that chances are the beta features are already incorporated in the V11 fully released version just that we might need to edit the CCL manually right?

Hi Timon,

I suspect that the version which I am using is an academic version which does not have the beta feature. If the beta features are incorporated, how do I go about enabling it? I read...

Hi Tom,

understand that some of the new features are not available in V11. i am actually studying the effect of surface roughness on airfoil. So far, SST model with transition predicted...

Hi,

does this work in V11( not beta version)? My school only has V11(not beta)..Anway Hi Tom! looks like we are looking into the same problem.

Hi Glenn,

how do I relate the intermittency variable to the transition point value I have? I read through the help files but could not find any clues. For example if I want to specify transition...

Hi Glenn,

I do have some predicted transition point data from journals for my aerofoil profile and they leads to reasonably good results. For my case, I started off with default values using the...

Hi,

is the editing of CCL to account roughness works in V11(not beta). Anyway just another question, I am now working on forced transition for my aerofoil simulations. I have divided the mesh...

Possible to account for surface roughness with SST model?

I need to account for surface roughness for my aerofoil simulations but found it is possible to input roughness height for the k-epsilon models and not SST. I am wondering is it possible to work...
