splitting patch into two boundary conditions using splitMesh
 

Dear Foamers;
i have been searching for how to make a slot in a cyclic wall, using bunch of utilities but i didn't succeed so i decided to post a thread here.


My problem is that i have two parallel walls, one on top of the other (that 's how i created them the first time for some boundary reasons that i posted before). everything worked perfectly, i could generate a flow and see the animation of the flow in the wind tunnel design. Now i want to made a small open windows (a slot) that connects the flow from the inside of the tunnel to the outside at the entry of the diffuser of inches, to do that i have to make a double slot for my two cyclic walls.
I tried TopoSet with boxtocell and patchtoface but it didn't work because i don't want to add nor extract a cell from my mesh since they have flow information that i need, then i found splitMesh in modifyMeshDict since all i want is keep the rest of the boundary condition as a wall, but change a small part of it, to, i don't know yet if zerogradient with zero velocity. But for now im just looking how can i work it out, or anyone has a better idea, utility tool to share with me.

Thank you everyone for the help!

Hello,
It is difficult to visualize the problem. You might get a help is you explain the problem using a picture/sketch.
