Suggestion needed for structured grid around airfoil O-grid
Hello Community,
I have been trying to create multi-block structured grid around airfoil.
With suggestions, I could create a decent pure O-grid around airfoil, using boundary layers. ( GEO File attached) Now, the ultimate aim is to create 4 more grid-blocks around that O-grid, using TFI ( image attached). Currently I have un-structured grid around O-grid.
For doing so I can think of 2 ways -
- I will need to define start of block 1,2,3,4 from the boundary layer end ( O-grid edge) towards domain boundary. OR 2)Define the points/curve of the O-grid block and then make boundary layer from airfoil to the block boundary curve.
Although option-1 would be best but I am not sure which of these options is possible ( if any?) Any suggestions/ Tips would be helpful ( GMSH 4.8, Win10)
Thank you
