The highlight of this release is the availability of a native Apple Mac version of Caedium. There are also various 3D selection, Properties Panel, geometry, physics, and particles enhancements for Windows and Linux platforms.

New Features and Enhancements

• Mac OS X (10.5 Leopard and 10.6 Snow Leopard) is now a supported platform, joining Windows and Linux
• Selection
  • Improved View Window selection performance
  • Use Ctrl key while selecting to add/remove to/from an existing selection in a View Window
  • Use Shift key while selecting to suppress Select dialog and select an entity in a View Window
  • Standard shortcut keys for list selection in Select dialog, i.e., Shift for range select and Ctrl for multi-select
• Properties Panel
  • Properties Panel checkboxes and sliders instantaneously apply changes, rather than requiring a focus change
  • Properties Panel adds vertical scrollbar as needed
  • Switch Tool Palette and Properties Panel tabs to show latest new entity, e.g., when dragging and dropping (DND) an Inlet boundary condition onto a face
  • Expand new properties when added to Properties Panel, e.g., when DND an Inlet condition onto a face
• Geometry
  • Import ASCII point sets (.pts) as vertices (geometry) and groups for easy spline fitting - ideal for defining airfoils [Builder]
  • Create a rectangular geometry grid (using the Rectangle tool) for easy geometry placement and construction [Builder]
  • Option to use a plane as the face geometry for the Fill tool [Builder]
  • Axes, Text, and Light entities now have a length scale to control their visual size to better match the overall scale of the geometry [Builder]
• Physics
  • Added Continuous and Continuous Rough wall function boundary condition options for nut (incompressible) and mut (compressible) - relaxes the constraint for y+ values to be outside the laminar sub-layer [RANS Flow]
  • Incompressible viscous flow uses the Cell MD gradient limiter by default for more robust convergence [RANS Flow]
  • Added new Physics->OpenFOAM->Singularity preference with options to Ignore, Report, or Stop (default) if a solver produces a singularity [RANS Flow]
  • Mesh->Tetulator->Diagnostics preference is on by default, in order to provide a measure of progress during tetrahedral meshing [RANS Flow|Panel Flow]
• Particles
  • Particles default Direction is Both
  • Particles default Time Step is 0.1s
• During Windows installation only provide options to associate Caedium with BREP, STEP, and IGES files - avoids the clutter of too many file formats to choose
• 'Learn More' button added to update notification dialog to give access to release notes

Bug Fixes

• Save would fail after joining faces on a volume with a Substance [Builder + RANS Flow|Panel Flow]
• Representing particles as ribbons or tubes and updating them during a simulation sometimes caused a memory overwrite crash
• Using time slider to reset simulation would cause subsequent solver operations to fail (Note it is still better to use Beginning button on the toolbar to reset the simulation)
• License activation would report 'Validation conflict' if license key contained a line return
• After the Select dialog was dismissed, the View Window needed an update to refresh part of the view masked by the dialog
• Analysis mesh, when no longer needed, was not removed and replaced by geometry facets [RANS Flow|Panel Flow]
