dualGPy

Python library to generate the dual graph of a generic mesh. Starting from the idea of the meshio library we developed a tool to read unstructured meshes, and give back the CSR representation of the Adjacency Matrix, relative to the dual Mesh. The idea is to use the ASAP (As Simple As Possible) rule.

Mesh class

The Mesh class has been developed as an abstact class to be specified for the 2D and 3D (WIP):

• Volume of the cells (Area in 2D);
• Area of the boundary faces (length of the segments in 2D);
• list of cells (starting from the meshio format we retrive the cells points);
• list of points composing the mesh.

Graph class

Built with the same philosophy of Mesh class it is able to operate and to build the CSR representation of the Adjacency Matrix.

Geometry class

A hierarchy of geometrical object to treat the 2D and the 3D meshes.

Utils

Useful utils for the pre and post processing (mesh management, like passing from a 3D to a 2D mesh and output printing)

Tests

The tests are being run through the Pytest suite. If you want to add a test follow the format proposed.

Examples

to look at an example have a look to the test.py script.`
