Unstructured Grid

What is an Unstructured Grid (UGrid)?

An unstructured grid is spatially referenced information made up of points (x, y, z locations). An unstructured grid may also have information about connections between the points. The connections between the points may define lines and faces; the faces may also be connected to define volumes.

Why UGrids?

One set of tools for working with all types of grids One set of display parameters for visualizing the grids One type on grid to be used with the toolbox Smaller code base with increased test coverage to make sure the tools and visualization works
