ICEM CFD Introductory Course-Introduction

•Gain understanding of basic functionality for

–Geometry import/editing

–Meshing (surface meshing, tetra, prism, hexa)

–Mesh Editing (smoothing, checks, individual element editing)

–Solver setup

•

•Propose best meshing practices

•Geometry Creation/Repair/Simplification

–Including Mid-Plane Extractions/Extensions

–Most geometry intended to be imported

•Powerful Meshing tools

–Tetra/Prism from CAD and/or existing surface mesh

–Shell meshing:  structured, unstructured

–Hex-dominant, swept, Structured hexa, Extruded quads, Body-fitted and stair-step Cartesian

–Hybrid meshing (merging, multi-zone)

–

•Advanced mesh editing

•Solver Setup

•Output to 100+ Solvers

•Post processing

•Scripting   … and much more…

•Use of many files

–Not one large common database

–For faster input/output

•All files are usually associated within a Project

–Establishes working directory

–Settings (*.prj) file

•Primary file types:

–Tetin (.tin):  Geometry plus

•Geometry entities and material  points

•Part association

•Global and entity mesh sizes

•Created in Ansys ICEM CFD or Direct Cad Interface

–Domain file (.uns)

•Unstructured mesh

–Blocking file (.blk)

•Blocking topology

–Attribute file (.fbc, .atr)

•Boundary conditions, local parameters & element types

–Parameter file (.par)

•solver parameters & element types

–Journal and replay file(.jrf, .rpl)

Record of performed operations (echo file)
