Struct TriangularMesh 

pub struct TriangularMesh {
    pub points: Vec<Point>,
    pub elements: Vec<Triangle>,
    pub boundary_edges: Vec<(usize, usize, Option<i32>)>,
    pub boundary_nodes: HashMap<usize, BoundaryNodeInfo>,
}

A mesh of triangular elements

Fields

points: Vec<Point>

Points/nodes in the mesh

elements: Vec<Triangle>

Triangular elements

boundary_edges: Vec<(usize, usize, Option<i32>)>

Boundary edges (node indices for each edge)

boundary_nodes: HashMap<usize, BoundaryNodeInfo>

Map from node index to its boundary condition type (if on boundary)
