Dear Roman, Thanks for your advice. I actually came across the Transfinite Line/Surface/Volume settings (also structured mesh). Using this, i was able to make a simple hex mesh.
The only small (not a deal breaker) peculiar behavior is that even though i set 2 nodes per line, when the 3D mesh is applied, an additional node is introduced in the middle of each line. Thus, say, cube is divided into 8 hexa instead of 1. Apart from that things look as expected. Kind regards, Denis.
