connect two different boundary layers
 
Hello everybody,
I am working to my degree project, I have to study the cavitation into a Venturi's tunnel.
I have a problem connecting two boundary layers using Gambit.
The first b. layer was made in this way:
uniform
first row(a)-> 0.001
Growth factor (b/a)-> 1.2
rows 4
internal continuity-> on
wedge corner shape ->on

The second B.layer :
uniform
first row(a)-> 0.008
Growth factor (b/a)-> 1.1
rows 4
internal continuity-> on
wedge corner shape ->on

the probem is that I have to connect them in a corner and the mesh quality is very very bad there.
Do you know what can I do to improve it?

thanks in advance

Max,
Thanks for your interest.
I was able to solve the problem but I had to change completely the mesh because the geometry was too complicated to connect propertly the two b. layer.
But Thanks again
