Modular Mesh Generation

The CENTAUR Modular Mesh Tool offers the important capability to generate derivative meshes from an original mesh by remeshing part of the geometry while leaving the rest of the mesh unchanged. The Modular Mesh Tool is used instead of the mesh movement tool when the geometric changes are quite large but localized.

Modular Process:
  • Generate mesh for original configuration using a multi-zone mesh
  • Remove one piece of the geometry
  • Add a replacement piece of the geometry
  • Generate a new mesh by combining the original mesh and a mesh created for the new part of the geometry.

Advantages:
  • Reduces time to create mesh for a new configuration
  • Minimizes setup time for the new geometry
  • Minimizes mesh changes when changing geometries
  • Automatically matches nodes, faces and edges of existing grid including mesh sizes

Example: Aircraft Pylon Design

This case illustrates the use of modular mesh generation during the design process. Here the shape of the pylon attaching an engine to the wing is varied. The shape changes are quite large requiring the use of modular mesh generation versus hybrid mesh movement. The first image shows the overall geometry with the engine region isolated in a separate zone. The two images below it show the two different pylon configurations that have been tried with this setup.
