1. Generate the first mesh

Goal

Generate segmentation figures, mesh.geo, and mesh.msh.

Configuration

Use the example parameters.toml and microsystem.png files.

Command

pymm -i microsystem.png -p parameters.toml -t mesh

How it works

The input image is segmented, external and interior contours are approximated, the Gmsh template is rendered, and Gmsh creates the three-dimensional mesh.

Result

The output folder contains four diagnostic PNG files plus mesh.geo and mesh.msh.

The generated files are written under:

output/
├── binary_image.png
└── extracted_border.png
└── interior_grains_border.png
└── interior_grains.png
└── mesh.geo
└── mesh.msh

Next

Continue with 2. Run the flow simulation.
