Chapter 2: Feature Changes in Fluent Meshing 18.0 Several features have been improved or added in Fluent Meshing Release 18.0. The following sections describe such feature changes: 2.1. Changes in Product Behavior from Previous Releases 2.2. Added Features

2.1. Changes in Product Behavior from Previous Releases • Interior zones between different cell zones will no longer be automatically converted to internal type when the mesh/case file is read. • The file size and time taken for writing case files in the Hierarchical Data Format (HDF) should be significantly reduced due to a change in the default compression level. • Domains are now updated to include new zones after face zones are remeshed and replaced. • The option for creating intersection loops for marked cross-object intersections has been changed to create only cross-object intersection loops.

2.2. Added Features The new features available in the meshing mode in Fluent include enhancements to existing features, and improved robustness through defect fixes. The following enhancements have been made: • Dialog boxes containing lists are expandable. • An octree option has been added for hexcore cell generation. This option will result in faster hexcore mesh generation but does not support hexcore generation up to boundaries. • The Inverse Orthogonal Quality measure has been added. • New scripting commands are available for marking faces; improving and remeshing boundary faces; and connecting overlapped face zones.
