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

If previous project was not completed, load the geometry F6_complete.tin and the mesh f6_surf.uns

•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
