I have been using the OF v1.5 simpleSRFoam - steady, incompressible, rotating reference frame - solver. Despite their being no documentation any where, I managed to decipher the example case ('mixer') provided and generate a "reasonable looking" solution.

I say reasonable because I have no data and haven't compared the solution to another solvers yet. While I finish up my doctorate, I have access to Fluent - in which I have run this case but yet the compare the solution to OF. One thing I can say OF runs _much_ faster than Fluent.

I wanted to start a thread where others who are using the solver can discuss usages and experiences with it.

One piece I would like to add, is the derived BC type 'surfaceNormalFixedValue' for rotating reference frame applications. For my case (see attached pictures), I had six inlets that I wanted to specify the normal velocity on but all the inlet patches had non-aligned positions and normal orientations. Needless to say it was a pain figuring them out so I could enter the velocity components for each inlet.

Anyone else using this solver please post thoughts/experiences here to share with all.

-Chris

Hello,
I tried to compile the simpleSRFFoam by using the backports in the 1.4.1-dev. But i got several errors.

I made it compile by adding the following lines to the make/options file.
-I./SRFModel \
-I./SRFVelocityFvPatchVectorField \

Mr Jasak could you correct that in the repository just for newbies.

Regards
Franz

Hi Franz, thanks for the replies.

Yes, the image I attached is from the solution using the simpleSRFFoam solver. I used VisIt to generate the image.

I have no experiences using simpleSRFFoam with OF v.1.4 - only v1.5 - so I will defer that question to the experts.

You can install v1.4 and v1.5 side-by-side, if that's an option for you.

Good Luck, Chris

Hi Franz:

have you ever succeed to compile the simpleSRFFoam in OF-1.4.1?

thanks

Hey Foamers,

im a newbie with OpenFoam.

Right now i try to add the Temperature to the simpleSRFFoam tutorial mixer.
after some time steps it stops and says "floating point exception".
And paraview shows that the temperature is infinity the whole time.
I think its an error in the initial conditions. But i dont know which one i could use!

Any ideas how to fix this?

Thanks you!

sarah

Hi Sarah

I know you have written your post long time ago, but may be you can help me. I am trying to add temperature to the solver simpleSRFFoam. To do that, I have created a new flux, phiAbs, calculated each time loop with the absolute velocity Uabs. Then I use this phiAbs in the temperature equation.

The solver compiles without errors, and the case iterates without problems, but the obtained temperature field corresponds to static conditions. I mean, is like the temperature equations is solved with velocity equal to zero, not with Uabs.

Did you add the temperature to the solver?. Any help will be useful.

Thank you very much

David.

Hi,

I know to you it might sound stupid. but what I would like to know that is the difference this one and simplefoam ?? I have also compared results of OF and FLUENT for other type od flow and I found OF little better.

Now i am trying to run mixer tutorial that use simpleSRFFoam so i follow these step:

Hey,

its possible that you have to make it before.

If there is a Folder called Make, just use wmake and it should build the app into your personal OF Folder.

Greetings,

Sarah

Dear Sarah,

can you tell me how to view complete rotor of mixer. as it shows only single rotor blade.
