Annotated example of a geometry with p3 symmetry. The fundamental domain is highlighted in yellow, the lattice vectors are shown as red arrows, and the side lengths a and b and the lower left corner γ are indicated. The unit cell mesh is shown with a colorful mesh, and the rest of the entire RVE is orange.
