Hi,

I have here a very interesting problem, which I would like to solve:

I built up an very simple mesh with perfect cell quality. Only two blocks (generated by splitting).
For one block I used the "refinement" function . ("blocking"->"pre-mesh params"->"refenement") (see figure 1)

After that I mirrored the generated mesh (without the blocking) with activated options “copy” and “merge nodes”. (see figure 2) As recommended I deleted the redundant upper surface shells with were inside the volume after mirroring.

When reading the mesh in fluent, the following error appears:
“Cell is missing face: Cell 1858, zone 9, at location ( 2.53906e+00, 1.04167e+00, 6.90234e-01).
Clearing partially read grid.
Error: Build Grid: Aborted due to critical error.
“

I looked for the coordinates given in the error notification by generating a point at this place. It was the first corner-cell after the refinement. (see figure 3)


What to do? Where can be the Problem?


Important: Reading refined mesh without the mirroring works as well as reading a mirrored mesh without refinement. IT’S THE COMBINATION, that makes problems?



Isn’t that interesting? Would be glad about some hints.

Thanks
