Hi everyone.

I haven't been doing much of CFD for quite a long, so it's a long time since I've been here and it's good to be back. Currently I've faced with one problem/task - is it possible to do the hexa meshing for the turbomachinery with ANSYS Meshing? Far and PSYMN showed that it's definitely possible with ICEM CFD, but what about ANSYS meshing?Had anyone tried to do this with it? I tried to look through the forum, but no luck .
What I'm particularly interested is to get the hexa mesh of the radial turbine flow channel with prism layers on hub, shroud and blade. Here is the example of the geometry.

What I tried so far:
1) sweep the mesh from hub to shroud and viceversa. The result is the same - because of highly twisted blade the mesh has skewed elements
2) slice the channel with the meridional surface and used Multizone method. This gave me a better results, as I was able to get hexa in the flow core with prizm layers around the blade and tet prizm layers at hub and shroud. Though I'm still strugling with it as it it too touchy.

Any ideas of how to make my dream come true?
