Unstructured grid

From Wikipedia, the free encyclopedia

Example of unstructured grid for a finite element analysis mesh.

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 list of the connectivity which specifies the way a given set of vertices make up individual elements.
