Hello everybody,

I am running different ABL simulations on OF30.x.
So far I have been using slip and zeroGradient conditions for the top boundary (declared as patch).
Now I am trying to adopt the fixedShearStress type as suggested on several articles. Unfortunately terminal comes up with such error:

--> FOAM FATAL IO ERROR:
Unknown patchField type fixedShearStress for patch type patch

What should I do?
I am a beginner user of OF, I can't really understand very well what to do.

Thank you

Hi Lolli,

You should add the line below in your controlDict:

libs ("libturbulenceDerivedFvPatchFields.so");

Hi Jie,

let me first thank you for the answer.
Unfortunately seems OF3 doesn't recognise this library.

Within TurbulenceModels folder I found derivedFvPatchFields, FixedShearStress is into that. I am using RAS model and into its derivedFvPatchFields it is not included.
It's like the presence of RAS doesn't permit to use it.

Is there a possibility to use RAS model and at the same time TurbulenceModels/derivedFvPatchFields?

Lolli
