Hi friends,

I have an error saying I used invalid 'RASModel' when I ran simpleFoam. Is it because information missing from 'system' folder? If so, from where can I copied standard RASModel dictionary?

Thanks a lot!!!

Hi Adikess,

I know there are three valid turbulencemodel types and I used RAS for running. But still this error came out. Do I need to amend my "U' "P" 'K' etc. dictionaries?

I read the error that you defined the model as "RASModel" but it should be "RAS".

Thanks Bazinga! Will try to fix it.

Dear Mark,
I wonder if you have solved your problem or not.
I have met a similar situation, while running the case of flow past a cylinder at: http://openfoamwiki.net/index.php/Be...coftac_ufr2-02
Could you please give me some hints?
Thank you in advance.
Best Regards,
Bill

Hi Bill,

You should define the TurbulenceModel as 'RAS' rather than 'RASModel'. The files you should check and amend should be in 'Constant' folder if I remember correctly.

Dear Mark,
Thank you for the reply.
If I ran the case directly, the error is like this:
unknown turbulenceModel type LESModel
Valid TurbulenceModel types:
3
(LES
RAS
laminar
)

However, if I change LESModel in to LES in constant--turbulenceProperties--simulationType, another error occurs:
keyword LES is undefined

By the way, I am using the version 3.0.1, and the files I am trying to run is version 1.6.
Any suggestions?
Thank you in advance.
Best Regards,
Bill

The syntax in the turbulenceProperties file has changed from 1.6 to 3.x. I am on my phone so I have no example but you can just check a tutorial in 3.x to understand how to set up the files.

Dear Bazinga,
Thanks for the suggestion.
I have checked the constant file for the turbulenceProperties, it does have changed from 1.6 to 3.0.1.
Thanks again.

Yes !! it was changed from 2.0 to 3.0
