25 Turning Mesh Criteria OFF Sometimes it is useful to turn a mesh criteria OFF. Criteria Direction Value Scaled? Max Edge Len large (scaled) Growth Ratio large 10.0 Sources none Max Gap large 10.0 (scaled) Num Circle Segments small Min Edge Len small (scaled) Max = Min will turn OFF Max Gap & Num Circle Segments Sources Max Edge Len Growth Ratio Max Gap Num Circle Segments Min Edge Len 25
26 Meshing Strategy 1. Set Max based on model dimensions Set Min = Max (turning off MG and NCS) No Sources Adjust Max & Min until satisfied (uniform coarsest) 2. Set Min to smaller value Say Min = Max/20 3. Choose MG or NCS as preferred curvature parameter (CP) Set other curvature parameter (OCP) OFF Adjust CP until satisfied Adjust Min as required (are smallest edges small enough?) 4. Adjust OCP (optional) 5. Add mesh sources as required Resolve flow features 26
