10 FINITE ELEMENT METHODS FOR FLUIDS Finite Elements: A triangulation of Ω is a covering by disjoint triangles (tetrahedra in 3D) such that the vertices of ∂Ω h, the boundary of the union of elements, are on the boundary of Ω. The singular points of ∂Ω must be vertices of ∂Ω h. A triangulation is regular if no angle tends to 0 or π when the element size h tends to 0. A
