2D Example Meshes

The directory containing the 2D input data is located here.

Synthetic Gaussian Data

  • Input distribution size : 1,000,000 cells
  • Uniform case: 30,949 triangles
  • Adapted case: 3,788 triangles
  • Gaussian me 10 uniform.png
  • Gaussian me 10 wl 1e-1 adapted.png

Commands to generate meshes :

Uniform : mesh file 

docker run -v $(pwd):/data/ cnf_tools tessellate2d  --input 2D_CASES/input/Gaussian2.vtk  --output Gaussian_me_10_uniform.vtk --uniform --min-edge=10

Adaptive : mesh file 

docker run -v $(pwd):/data/ cnf_tools tessellate2d  --input 2D_CASES/input/Gaussian2.vtk  --output Gaussian_me_10_wl_1e-1.vtk --weight-limit=0.05 --min-edge=10


GPDGK16Numerical_140519

The 2D case created by extracting a 2D slice at X=50 out of the 3D distribution (see 3D case below) GPDGK16Numerical_140519

  • Input distribution size : 10,000 cells
  • Uniform case: 7,587 triangles
  • Adapted (min_edge = 2) case: 623 triangles
  • Adapted (min_edge = 0.5) case: 1,409 triangles


  • GPDGK16Numerical 140519 X50 me2 uniform.png
  • GPDGK16Numerical 140519 X50 me2 wl 1e-1.png
  • GPDGK16Numerical 140519 X50 me0.5 wl 1e-1.png

Commands to generate meshes :

Uniform : mesh file 

docker run -v $(pwd):/data/ cnf_tools tessellate2d  --input 2D_CASES/input/GPDGK16Numerical_140519_X50.vtk --output GPDGK16Numerical_140519_me_2_uniform.vtk --min-edge=2 --uniform

Adaptive :(min_edge = 2) mesh file 

docker run -v $(pwd):/data/ cnf_tools tessellate2d  --input 2D_CASES/input/GPDGK16Numerical_140519_X50.vtk --output GPDGK16Numerical_140519_me_2_wl_1e-1.vtk --min-edge=2 --weight-limit=0.1


Adaptive :(min_edge = 0.5) mesh file 

docker run -v $(pwd):/data/ cnf_tools tessellate2d  --input 2D_CASES/input/GPDGK16Numerical_140519_X50.vtk --output GPDGK16Numerical_140519_me_0.5_wl_1e-1.vtk --min-edge=0.5 --weight-limit=0.1

Note : By using min-edge less than 1 we are essentially generating triangles with an edge smaller that the input pixels. Using values much smaller than 1 is not expected to help the discitization since we are esetially packing more element into a pixel which has constant value.

OBS_ALU_Y50

  • Input distribution size : 10,000 cells
  • Uniform case: 7587 triangles
  • Adapted case: 1018 triangles

The 2D case created by extracting a 2D slice at Y=50 out of the 3D distribution (see 3D case below) OBS_ALU


  • OBS ALU Y50 me 2 uniform.vtk.png
  • OBS ALU Y50 me 2 wl 1e-1.png

NT_140519

  • Input distribution size : 10,000 cells
