### *class* ansys.meshing.prime.lucid.Mesh(model)

Provides methods for users who are new to meshing.

This class also serves as a tutorial for commonly used meshing workflows.

The `Mesh` class provides these functionalities:

- Surface meshing with constant and variable sizing with triangle or quad dominant mesh
- Volume meshing with prism, tetrahedral, and polyhedral elements
- Surface wrapping
- Helper method for creating zones from labels
- Helper methods for reading and writing files
