4.2.1 Introduction - Binary Tree Meshing
Binary Tree Mesh is the proprietary meshing technique used by Simerics-MP/ Simerics-MP+. It is used to create a mesh inside and or outside any “water tight” geometry defined by CAD Surfaces. It starts with a single hexagonal parent cell, encompassing the geometries of interest, and then sequentially subdivides and/or cuts successive generations of cells until the desired resolution and representation of the original surface is obtained.
This provides accurate reproduction of the original geometry but preserving:
- Edges based on the Critical Edge Angle.
- Curvature based on the Curvature Resolution.
The Binary Tree Mesh provides high quality grids for numerical efficiency and accuracy. It is very efficient in creating a mesh for most complex arbitrary shapes. Figure 4.15 shows the Binary Tree Mesh on a motorcycle.
