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

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


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.

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!
