VORONOI is a parallel, scalable control volume tessellation generator, built for use in subsurface flow and transport solvers.
The program accepts a Delaunay mesh composed of one of four element types: triangles, tetrahedrals, quads, or hexes.
It then finds the Voronoi dual or median of that mesh, and writes it in a solver-specific format:
- FEHM (
.stor) - PFLOTRAN (
.uge) - TOUGH (
MESH) - HDF5 (for general use;
.h5)
VORONOI works as a standalone MPI application or as a serial command in the LaGriT mesh generator.
- Accurate calculation of Voronoi/Median cell volume and cell face area in 2D and 3D
- Reads AVS and LaGriT input files (LGI)
- Outputs to FEHM, PFLOTRAN, TOUGH, and HDF5
- Outputs visualization of control volume cells
- Assigns ROCK coefficients based on node attributes (TOUGH)
- Automatic element assignment of isotropic / anisotropic permeability coefficients (TOUGH)
- Removes duplicate and negligable coefficients (FEHM)
- Built with PETSc for parallel execution and sparse matrix data types Cross-platform & open source
