Thank you very much,
It is the simple model, in reality it is needed to mesh the electrical engine, and as the hexa mesh gives in ~8 times less elements as tetra for coupled analyze it is critical....

So, there is a transformer and the air around it.
The coils, stator, gaps are blocks.
How better to mesh the air?

or possible there is any way to build cartesian mesh based on the surface mesh or adjusted blocks?

by the way. I've observed that the mesher sometimes change the base surface mesh. So it will be helpfull to lock surface nodes before tetra octree meshing.

In my case It merges, however at first the quality of tetras is poor:
Histogram of Quality values

So Simon, do you think?
to mesh the 3D air around the hexa topology mesh - the best way to use:
1) Robust (octree) (no prism and no hexa-core) based on adjusted surface existing mesh parts;
2)...

The hexa-dominant give the better result (with the same elements types - less nodes&elements quantity), however the mesh quality is poor. How could it be really improved?
