TGrid 3.5 is a maintenance release with a focus on stability. The most notable advance in TGrid 3.5 is the improvement to the tet-initialization and tet-refinement stage of 3-D tetrahedral meshing. This will provide higher quality 3D meshes in larger and more complex geometries. This also provides a solution to the situations when the boundary mesh consists predominantly of quad-split triangles, often used in external aerodynamics modeling. In addition, TGrid 3.5 provides two methods (perturb or insert nodes) to automatically ensure successful meshing.

Further enhancements include:

• A full set of "hot-keys" for boundary modify commands
• Domain read and write capability
• Enhanced node merge
• GUI panels for projection and proximity refinement commands
