how to set multi-BC on a internal face?
 
1 Attachment(s)
Hello guys!

i am totally new with OpenFOAM and I got a problem with the BC setting.

Problem:
there is some chemical reaction happened on the interface between two blocks. There is some special BC on those faces. But i can not choose those faces and set the "boundary" in the "blockMeshDict", because they are internal faces.

How can i do? Should i try the "topoSet" and " createBuffles"?

Pls help me, help this poor man...
Thanks a lot ;)

yep, those are good options, look pimpleDyMFoam to see how to use these utilities

thanks nimasam;)
i will try it.

But i think the "pimpleDyFoam" is a dynamic solver, in my case, there is no "moving part", the reaction surface is exactly between the 2 blockes. Can i maybe use the pimpleFoam or simpleFoam with some specical BC settings?
