[ICEM] Meshing adjacent wall geometry and simple ICEM questions

For the quality option, it's obvious that the index control is not the solution.
But for the fact that blocks sometimes disappears when you click "undo", that's obvious it may be the solution.

About the "undo" which doesn't work after you saved your project, it's just an option : Settings -> General -> Clear undo after saving project or geometry

About your quality issue, I have never heard about that kind of matter, so maybe someone else could help here ?

I confirmed - the quality of the initial pre-mesh always worsens after I apply boundary conditions to the named surfaces in the output for fluent.

So each time i want to export mesh I have to save my work as a separate project so that i can "damage" it. And if i want to make some corrections - i delete this project and go to the previous one.

Not possible. May be you are also also including some dead mesh

I am not doing anything with the mesh at that point. All I do is define boundary conditions in the 'output tab'
After that if i want to look at 'pre-mesh' it asks to recompute, i say yes and i get quality bars starting from zero.

If you have already converted the pre-mesh into unstructured mesh, ICEM should not ask you to recompute unless something has happened intentionality or unintentionally

Or this may be due to mismatch in boundary condition and association of edges to curves. Or may be you have curves in different part and surface in different part.

once you have convert your mesh into unstructured mesh, you don't anymore to look at the pre-mesh.
if you want to look at the quality of your mesh, go to "edit mesh" -> "display mesh quality".

as Far said, it's weird you need to recompute if you didn't change anything at all ...
