Tips & Tricks for Hex "Brick" Meshing - ANSYS e-Learning

Hex meshing provides computational efficiency where less nodes and elements are required to achieve high solution accuracy.   Assuming the geometry is amenable, a brick meshed model can save orders of magnitude of CPU time, and require significantly less RAM and disk space over the all tetrahedron mesh, often with better accuracy.  Also, a mesh where all elements contain three mostly parallel faces is easy to check, since the exterior faces provide enough detail to fully comprehend the entire mesh geometry.  However, unlike tetrahedron meshing that can be performed on nearly any geometry, hex meshing requires a certain amount of topology cleaning and decomposition to achieve an all or nearly all brick mesh.

CAE Associates’ Vice President Peter Barrett guides you through key tips and tricks for geometry clean-up and  geometry "slicing".  You will learn how to:

  • Identify geometry that can easily be modified to be Hex meshable
  • Develop techniques to prepare topology for meshing and/or diagnose why a model doesn't sweep
  • Use size control and when to use Sweep and MultiZone Methods
  • Understand how to combine Hex and Tetrahedron elements in a flow through mesh analysis

If you are only using all tetrahedron meshes in Workbench Mechanical and want to learn some tips for building a better brick mesh, you should view this e-Learning session to expand your analysis expertise.
