•First,
extrude prism mesh from standalone surface mesh
–“Bottom up” approach
–Could also extrude into existing volume mesh (traditional
method), “top down” approach
•Generate
rest of grid
–Farfield volume
–Delauney
•Use
density region
–Define mesh size for refinement
–In area where no geometry exists
•Create Hexa core
–For majority hex fill in far field
–
•Choose File > Open Project
–To load previously saved surface mesh and geometry
–Browse to Wingbody working
directory
–Load previous project
•Set global prism parameters
–Mesh
> Global Mesh Setup > Prism Meshing Parameters
–Set Growth
law to exponential
(default)
–Initial
height = 0
•Height determined automatically so that
last prism is similar volume to adjacent tetra
•Proportional to size of triangle
–Height
ratio = 1.2
–Number
of layers = 5
–New
volume part = LIVE
•Scroll down to access
•We will create prism from a
surface-only mesh
•The volume part is necessary when
extruding from surface mesh
