How can I use patchtopatchinterpolation?

aperture · September 26, 2010, 21:41

Dear all,
I'm a new commer of OpenFoam.
I want to do 1-way FSI. For mapping the presure field on the surface of the solid, I may need to run patchtopatchinterpolation utility. How can I run it?

THX in advance.

Hi,

I am not sure if there is a patchToPatchInterpolation stand-alone utility (please correct me if I am wrong)
but the code is all there for you to use.

You have to include patchToPatchInterpolation.H in your solver, and you declare the patchToPatchInterpolation like this:

Code:

patchToPatchInterpolation fromPatch_To_toPatch_Interpolate
(
 mesh.boundaryMesh()[fromPatchIndex],    // from patch
 mesh.boundaryMesh()[toPatchIndex],     // to patch
 intersection::FULL_RAY,
 intersection::CONTACT_SPHERE
 );

Different intersection methods can be used.

And then to use the your patchToPatchInterpolation, you would do something like this:

Code:

vectorField interpolatedQuantity = fromPatch_To_toPatch_Interpolate.faceInterpolate<vector>
(
quantity.boundaryField()[fromPatchIndex]
);

You can use pointInterpolate too and interpolate scalars and tensors too (I think).

Hope it helps,
Philip

I'll try that.
Thanks !

Hello everyone
I am working with bubbleintertrackFoam solver to simulte a bubble in a still liquid column. I am getting an error as

--> FOAM FATAL ERROR:
Error in B-to-A face patchToPatchInterpolation.

From function freeSurface::makeInterpolators()
in file makeFreeSurfaceData.C at line 105.

Can anyone help me to understand meaning of above said line or suggest me what to do.
