Unstructured grid

Unstructured grid

An unstructured grid is a tessellation of a part of the Euclidean plane or Euclidean space by simple shapes, such as triangles or tetrahedra, in an irregular pattern. Grids of this type may be used in finite element analysis when the input to be analyzed has an irregular shape.

Unlike structured grids, unstructured grids require a listof the connectivity which specifies the way a given set of verticesmake up individual elements.

Ruppert's algorithm is often used to convert an irregularly shaped polygon into an unstructured grid of triangles.
