Creating Hex Boundary Layer Mesh and Unstructured everywhere else
 
2 Attachment(s)
Hi all,

I am studying wing tip blowing and I am trying to produce a structured mesh on my wing and on the boundary layer, whilst having an unstructured mesh around the wing.

I have tried different methods to obtain this but I am not getting what I want out of Ansys Mesher. I have used a combination of Multizone, Inflation and Face Sizing (on the wing).

I also need a fine mesh on the wing tip as this is where my UDF will be hooked onto.

If anyone has any suggestions for me, I would very much appreciate it.

Problem Info: 8m Wing,
(12m Height, 13m Width, 10m Length from TE) Domain,
NACA0012 Aerofoil (1m Chord)

EDIT: Sorry I forgot to add a screenshot.

However, my problem has now changed. I now do not need a boundary layer mesh as I will be modelling with inviscid solver. So by using the inviscid solver, this will remove wave and viscous drag, and leave only the lift-induced drag being calculated.

But, I need to create a structured mesh over the geometry and the domain. I also need very fine cell sizes on the wing tip as this is where my UDF will be applied to.

Info: I am studying the effects of wing tip blowing as a means to reduce the lift-induced drag on the wing.

Thanks

if u attach ur model as a screen shot then it will be very clear!!!!!
