Hi,

I want to perform a conjugate heat-flow simulation and thus needs to mesh multi regions, including fluid and solids.

A simplified case is attached which includes a chamber and a plate, as well as all needed files to run.

Strange cells are generated by snappyHexMesh at the interface between the chamber and the plate. These strange cells belong to the chamber and is a thin layer. In addition they seems not connected to the lower cells of chamber.

Meanwhile besides the /chamber/patch/chamber_to_plate, there is an extra patch with the name of "plate" under /chamber/patch/ in paraView. ParaView shows this patch is composed of double layers of surface but in original stl surface "plate" it is a single layer surface.

In the attached figures, all cliping is done at (0,0,0) with normal of (0,1,0).

The version of openFoam I used is v2206.

Any idea is appreciated!

Thank you in advance!
