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
• Support for point datasets and cell datasets
