Mesh Generation of Complicated, Sliced Structures

Numerical simulation is used extensively in numerous industries for design, dimensioning and validation purposes.  The first computational step in a numerical simulation involves constructing a mesh in the computational domain that represents the physical or geometric domain of the phenomenon under investigation.  This mesh replaces the original, continuous region of the phenomenon with a finite network of geometrically simple and bounded elements, each of which can be described mathematically.

Mesh construction if often a significant bottleneck for numerical simulations, both in terms of actually creating the mesh and in terms of its impact on the simulation itself.  The mesh structure, and the size and shape of the mesh elements, can have a tremendous impact on the stability of a numerical simulation and on the accuracy of its results.

There are many mesh generation methods but no one method can be considered a universal tool.  Mesh generation requirements greatly depending on the specific application and its computational domain features.

The NeurOK Software team has years of experience in developing custom, high-performance mesh generation tools for both government labs and commercial customers.  One of the world’s largest corporations has contracted with the team to develop software for the automatic subdivision of models which represent multi-material, sliced structures.  Such models are widely used in geology, medicine and various other industries.

For this project the team implemented an integrated set of effective, robust, mesh generation tools which included the following:

  • Triangulators and Voronoi grid generators for subdivision of multiply-connected domains with constraints
  • Tools for automatic generation of structured and unstructured meshes for surfaces with discontinuances and cuts and for 3D heterogeneous sliced domains with faults and cuts
  • Adaptive tetrahedral, prismatic and hybrid mesh generators
  • Mesh refinement, mesh simplification and mesh optimization tools
  • Mesh generators and tools for volume and surface subdivisions using mesh templates
