Tetrahedral mesh generation - robustness test Presentation Transcript

  • 1. Tetrahedral mesh generation Robustness test Schlumberger public 1
  • 2. Behind the scene – Tetrahedral Mesh Generation• Maybe the only volume representation that can:  Be used as a support for dynamic computations/processings  Capture the full complexity of a geological model  Be easily locally/globally adapted to a given problem Schlumberger public 2
  • 3. Behind the scene – Tetrahedral Mesh Generation Schlumberger public Fine grained control of mesh anisotropy and heterogeneity 3
  • 4. Behind the scene – Tetrahedral Mesh Generation Unstructured mesh Input data generation robustness test Schlumberger public 532 random fractures, 3 faults 4
  • 5. Behind the scene – Tetrahedral Mesh Generation Random angles, random intersections Input data Schlumberger public No preprocessing of input data 5
  • 6. Behind the scene – Tetrahedral Mesh Generation Unstructured mesh construction Schlumberger public ~300k elements A large majority of elements have a nice shape/aspect ratio 6
  • 7. Behind the scene – Tetrahedral Mesh Generation [Solid slice through the mesh] Unstructured mesh construction Schlumberger public All fractures are represented by triangular facets in the mesh 7
  • 8. Behind the scene – Tetrahedral Mesh Generation Unstructured mesh construction Schlumberger public Integrating fauted horizon surfaces into the mesh 8
  • 9. Behind the scene – Tetrahedral Mesh Generation [Upper layer hidden (transparent)] Schlumberger public Tetrahedral mesh containing fractures, faults and horizons 9
