Two types of 2D grids are supportted by GMS, mesh centered and cell centered. The two main techniques used to create 2D grids are: the Create Grid command and the Map -> 2D Grid command. A 2D grid can also be created from an existing 3D grid using the Grid -> 2D Grid command in the Grid menu of the 3D Grid Module. A GIS grid may also be imported.
Each of the cells in a 2D grid can be active or inactive. An inactive cell is ignored when contours, fringes, or vectors are displayed on the mesh.
Each cell in the grid has an associated material type. When a new grid is created, the material type for each cell corresponds to the default material type. The default material type can be set using the Materials Editor command in the Edit menu. A new material can be assigned to a cell or a set of cells by selecting the cell(s) and then selecting the Properties command from the Edit menu.
Rows and columns can be added to an existing 2D grid by using the Add i Boundary tool and the Add j Boundary tool. Also, the interface between a row and a column can be moved by using the Move Boundary tool.
