For anyone who may read this thread in the future, OpenFOAM foundation has adapted a similar approach. Unfortunately, this update is available only for OpenFOAM-dev but eventually, it will be part of the upcoming versions.

It is commit OpenFOAM-dev : 028617c30c68a66c00a3cda28e8706709f9f9e10

Thanks Hassan,

I missed that function definition when I was copying over the functions from 2.3. Sometimes it takes a second set of eyes! Now I just have a floating point exception somewhere I've got to find haha. Hopefully, shouldn't be too hard.

Thanks again for your help!

Thanks for reply.
I have uploaded my files, please go through this. Yes it a CFD support version downloaded from following link :
http://www.cfdsupport.com/openfoam-in-box.html

it is OpenFoam in box based on openFoam 3.0.x

For compiling my turbulence model I followed the steps as given here:

You have a similar problem, the definition of one function is missing:
You called it at line 110.

volScalarField Ck() const;

Best wishes,

Thanks for reply,

I will try to do what u said. But can u please tell me how can I learn to understand the OpenFoam codes ? can u please provide me some study references for that ?

Actually, this problem is related to C++. There are many C++ online material and books. Regarding this problem you need to review C++ source files organization, usually at the end of any C++ book. Please check this link from C++ wikibooks [LINK]

Dear Hassan,
Still the problem is not solved. My turbulence model is compiled successfully but while running my case i am getting following error :

reactingFoam: symbol lookup error: /home/adlak/OpenFOAM/adlak-3.0.x-cfdsupport/platforms/linux64Gcc49DPInt32Opt/lib/libdynamicSmagorinsky.so: undefined symbol: _ZNK4Foam9LESModels18dynamicSmagorinskyINS_15EddyD iffusivityINS_18ThermalDiffusivityINS_27Compressib leTurbulenceModelINS_11fluidThermoEEEEEEEE2CkEv

I have uploaded my files.

Try this to find the missing link;

I have also encountered this Duplicate entry problem. Have you solved it? Thank you.

Hello Hassan
I read your blogpost and it helped me a lot. I am currently trying to implement a recent k-Omega SST model in OpenFOAM7. I obeyed all the instructions in the blogpost and read the previous posts in this thread but I am still facing the same "Unknown RAS Model" error.
I have not changed the original OpenFOAM repo on my device to keep it intact and I have written the name of the library correctly in controlDict.

Thanks

Dear Hassan,

I copied your files and put them into phasecompressibleturbulencemodel folder. But it failed to be compiled. The error is in the following:

Hey Dhruv,

I'm facing the same problem. I'm not sure, if it becauses of Windows. Did you solve it?

Hi, if you use linux there are no this problem.

[sunjh]

Hi, is there any method to fix this problem on windows?

I also tried to ask this before. However, I found the method is available in linux. I gave up this issue. In my opinion, you'd better use linux-openfoam.
