  • Orography & Bathymetry V2.0 ready for download!
  • THANKS FOR VISITING THIS PAGE, I HOPE YOU WILL FIND IT INTERESTING, AND MAYBE USEFUL

git clone https://bitbucket.org/mmesh3d/mmesh3d.git
 
 


  • A 3D semi-structured mesh generator for domains with orography and bathymetry
  • QUAD-TREE based static grid refinement (2D version)
  • NOTE on MULTIBLOCK: The multi-block structure is being recoded since he current versions do not allow this option in 3D.

  • Main features:
  1. Structured ELLIPTIC mesh generator for 3D volumes [1]
  2. Quadtree mesh refinement
  3. Boundary orthogonality and automatic grid control [9]
  4. Generation of Hexahedral and Prismatic elements
  5. Topography readable from Digital Elevation Model (DEM) data files (from NOAA)
  6. Topography readable from the ETOPO Global Relief model of NOAA [5,6]
  7. Cube sphere

to all we now know and understand, while imagination embraces the entire world,
and all there ever will be to know and understand."
