Triangular mesh

class freshkiss3d.TriangularMesh

Freshkiss3D two-dimensional triangular mesh.

Parameters

• TG (geomalgo.Triangulation2D) – Triangulation containing: Vertices x-coordinate, Vertices y-coordinate and Array of shape (triangle_numbers, 3), giving the 3 vertices of each triangle.

• boundary_labels (array, int32, 2D) – Array of shape (boundary_edge_numbers, 3), giving for each boundary edges: - its first vertice, - its second vertice, - its label, to apply boundary conditions.
