ICEM CFD Introductory-Volume Meshing

•Define Volumetric Domain

–Optional

•Recommended for complex geometries

•Multiple volumes

–Geometry -> Create Body

–Material Point

•Centroid of 2 points

–Select any two locations whose mid-point is within volume

–Preferred

•At specified point

–Define volume region by “point” within volume

–By Topology

•Defines volume region by set of closed surfaces

•Must first Build Diagnostic Topology

•Entire model

–Automatically define all volumes

•Selected surfaces

–User selects surfaces that form a closed volume

•Hexa-Dominant

–From existing quad mesh

–Good quality hex near surface

–Somewhat poor in interior

–Typically good enough for static displacement

–Not covered in detail here

•Cartesian

–Automatic pure hexa

–Rectilinear mesh

–Staircase or

–Body fitted

–Fastest method for creating volume mesh
