ICEM CFD Introductory Course Prism Meshing – Workshop 2 Wingbody

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
