Boundary layer Mesh for external aerodynamics

Recommended Posts

Hi,

 

I am trying to create a boundary layer mesh around a sphere. It is non uniform boundary layer, what I mean is I am fully aware of how to create a volume mesh with boundary layers. But what I dont know is how I can create a varying number of boundary layers within the domain. Say closer to the sphere, I want 20 layers and near the inlet I need 10 layers. Is there way to create this within Hypermesh?

 

Thanks

Hi Rahul,

 

Thank you. Please find the snapshots attached. Geom.jpg is the domain that I am trying to mesh. It's a simple one with sphere, rod and a wire wrapped to it inside a box.

The picture1.png is the mesh that I am trying to replicate in Hypermesh. You can see it is jaggered with multiple refinement zones and different meshing parameters for each of them. Can I do this is in Hypermesh, if yes can you please help?

 

Thanks

Hi @Rahul R 

Any pointers will be helpful.

 

You can not make this such CFD mesh (as your image) with Hypermesh, IMHO (maybe I'm wrong? @Rahul R ?)

You can not change the number of BC layers neither. But it's possible to make layers with variable thickness.
