hi i am modeling cylinder piston motion and during piston motion i get following error message.

"Coalesce-rib-faces:cant interpolate data .zones of different type detected"

please tell me what THIS MEANS.

i shall be very thankfull to you

Hi,
I am facing the same problem and wondering if you were able to solve it.

Thanks in advance

Hi! I faced the same problem and the issue was a face split that I made in Design Modeler. These face splits matter, even if they aren't used explicitly during the meshing. I suggest do a dynamic mesh preview in Fluent to determine which geometry feature bothers the mesh movement. I hope my answer was helpful.

hello dear
you must change your boundary condition of "walls to interface" in "direction" of your interface. in other words you must change all boundary conditions that slide through "motion wall" to interface and then define them in manual interface. in the last you have all boundary conditions of slider with "interface" mode, "no" part of that.
