Dears,


I am currently stucked at the barely end of my mesh generation with the snappyHexMesh routine of openFoam 2106.


After castellating and snapping my initial mesh, I would like to add some boundary layers at the surface of my object. Something that the routine seems to do well, but once it comes up to the final balancing, it couldn't recognize / find / whatever my front and back patches. I find it weird since it did it well for previous balancing.


For you to better understand what I am working on, I want to simulate a wind turbine in a turbulent flow. So I import the {*.stl} files of the turbine and a cylinder which will represent the boundary between a rotating and a static mesh. My initial mesh is generated by the blockMesh routine and is composed of basic hexahedrons. I refine these near the turbine as well as near the cylinder, and I refine the region inside the cylinder as well. I would specify that I am running in parallel, on 4 processes.


Please find the error message attached. And do not hesitate if you need further information !
