How to add collisionModel in reactingParcelFoam?
 

Hi Foamers,

I am quite new to OF, now I am trying to add particle collisionModel in reactingParcelFoam? But I am poor in C++.

Could someone give me some suggestion or tutorials about how to achieve this?

Thanks

Dear chpjz0391

Read this report,the author described how to add submodels:

but remember that you must addressed your modified lagrangian/intermediate library in your solver/Make/Options. else your solver didn't find it you can't use your new submodel.

Hi bijian，

Thank you very much. I will try.

Kind Regards.

Hi bijian,

Sorry to disturb you again. I have followed that report, but it did not work.Below is my step:

1. I copied CollisionModel folder from src/lagrangian/intermediate/submodels/Kinematic to src/lagrangian/intermediate/submodels/ReactingMultiphase
2. I copied makeParcelCollisionModels.H to makeReactingMultiParcelCollisionModels.H under src/lagrangian/intermediate/parcels/include
3. I changed "makeParcelCollisionModel_H" to "makeReactingMultilParcelCollisionModel_H" in the new makeReactingMultiParcelCollisionModels.H
4. wclean and wmake libso
5. I added collisionModel under reactingCloud1Properties in constant

When I run the case, it doest work. I mean the collision submodel was still not available.

Can you give me some suggestions?

King Regards,

Dear chpjz0391

Is your modified lagrangian library ( intermediate ) in Home directory??

I know where is the problem. I forgot to define the makeReactingMultiphaseParcelCollisionModels.H
under parcels/derived/basicReactingMultiphaseParcel.

But after I defined that, I got another error. show in the picture.

I have no idea what is going on.

Hi bijian,

I have solved my problem, I forget to modified the files under the parcels/derived/basicReactingParcelFoam and cloud/derived.

Cheers,

Hi Bijan

I tried to use the methodology described in the report to adda new CloudFunction Object. So i recompiled the whole intermediate library inside my $FOAM_RUN directory.

But when I run the solver it says that the functions are defined twice.

when you says:
That means that the solvers has also to be recompiled in the $FOAM_RUN directory, with the modified intermediate library, in order to be able to use the new model???

Thanks for your help

Dear Sylvain

At the first, test that your new "cloudfunctionobject" have been added to your solver or not!!!

That warning was not important.

yes. do his steps:

Best wishes.

Thank you so much Bijan

actually it was those two lines i didn't know how to write

but you were right in the first place, the solver didn't find my new cloud function object.

I don't know what is wrong as i have declared it in the makeParcelCloudFunctionObjects.H

What I don't understand is that we have know two intermediate libraries side by side with two different list of cloudfunctionobject. is it the fact that i compiled my new solver with my new library which guarantees that he using my new library?

Best regards

Sylvain

Hello


I am facing the exact same error right now as the picture you posted before this message. Can you please tell how did you resolve the issue?

@poseidon_CFD
As I understand, you have to modify parcels/derived/basicReactingMultiphaseParcel and that of cloud/derived/ since the error massage questions about the parcel type.

Has anyone managed to successfully add collisions to reacting parcels on a later version of OpenFOAM (5+). If so could you please provide the source code for the modified lagrangian library.
