Summary0000534: kOmegaSSTSAS requests RASModel RASProperties
DescriptionChanged motorbike pisoFoam RAS-LES tutorial:
RAS - kOmegaSST
LES - kOmegaSSTSAS

At the very first iteration of the LES simulation after the k equation is solved the solver quits with the following error:
--> FOAM FATAL ERROR:
request for RASModel RASProperties from objectRegistry region0 failed available objects of type RASModel are

0
(
)

From function objectRegistry::lookupObject<Type>(const word&) const
in file /home/tibornyers/OpenFOAM/OpenFOAM-2.1.x/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 131.
Steps To Reproducerun ./Allrun script
Additional Information
At cfd-online.com the first thread that discusses the issue was started in 2010. Since I couldn't find any kOmegaSSTSAS tutorials the community may misunderstand something about the use of this LES model.
TagsNo tags attached.

Your case is set up to use wall functions. The kOmegaSSTSAS is a low-Re model.

This case was set up for RAS turbulence, and applied RAS-based wall functions. If you want to convert the case to use LES, you will need to update the boundary conditions accordingly.

For the kOmegaSSTSAS model, we have not implemented a k-wall function boundary condition for LES - if you can supply a reference we could add the functionality in a future release (or quicker under a support contract).

In the meantime, it is probably more appropriate to set a nut wall function, and apply fixed-value (0) on k.

Thank you for the information, sorry for my misunderstanding!
