With mapped hexa blocks, the number of nodes on parallel edges must match (except where they are multiplied by a refinement factor).

For instance, if you have 10 nodes across one index, it must be the same the whole way across your model. You can't just set one particular edge to 7 nodes... that 7 must propagate.

The option to propagate distributions is for the "distribution" (the mesh law, initial spacing, etc.), the number of nodes must be propagated...

@Far... It is a defect and has been reported. It should be sorted out for 14.5.

Thankyou very much for very detailed analysis about problem and your time. As I can see things are improving at rapid pace at ANSYS (especially due to Sr product manager )

I saw one of your presentations where you have explained that by deleting (permanently) the inner block of cylinder we can avoid this constraint on parallel edges.

I made the youtube tutorial on how to create mesh of circular cylinder in ICEM.
This is two part video tutorial.Cylinder meshing tutorial
