Unstructured mesh generation for geological numerical simulations

Description: Generation of unstructured mesh conformal to geological interfaces

  • Adaptive tetrahedral meshing: control the size of the mesh elements according to the geological feature proximity (horizons, faults or wells) to increase the accuracy of the numerical simulation
  • Hex-dominant meshing: conversion of a tetrahedral mesh into a mixed-element mesh (tetrahedra, pyramids, prisms and hexahedra) to reduce the number of mesh elements and the node valence
  • Software development: implement external libraries in C++ using fast and light mesh data structures and parallel implementations: RINGMesh and VorteXLib
