There is no concept of internal boundaries. Instead create a cyclic baffle. This will not affect the flow but allow you to do 'patch things'.

Use createBaffles to convert a set of internal faces into baffles on an (existing) cyclic patch.

Dear mattijs,

Thanks for you answer.
But I am confused. I just want to create this plane, and sampling data in this plane.
First I generate fluent mesh, and set this internal plane using "interior" boundary.
when converted to Foam mesh, this plane becomes a faceZone called "int_SAMPLING".

I use [ createBaffles int_SAMPLING samplingplane ] , then this internal plane becomes two sided wall.

Then what should I do to create cyclic baffle ?

Thanks .

Hi everyone

Thanks for posting this guide of how to sample an internal plane. It was of great help so far.

However I got an additional question for that. I already ran tons of simulations and I would like to have these internal faces values. It works ok with mapFields for the general fields, but not for phi for example.

Do you have an idea how I can get other than the standard fields onto this "new" mesh with internal faces?

Cheers Adrian
