Creating and Editing 3D Grids

Two types of 3D grids are supported in GMS: cell centered and mesh centered.

Creating 3D Grids

Two techniques are available for creating 3D grids: the Create Grid command in the 3D Grid Module and the Map -> 3D Grid command in the Map Module. When a 3D Cell Centered Grid is created two different viewing modes are available.

Editing 3D Grids

Each cell in a 3D grid has attributes associated with it. Each grid cell can be specified as active/inactive and each cell has a material associated with it. To edit the cell attributes associated with a numerical model see:

• Editing MODFLOW Cell Properties

• Editing MT3DMS/RT3D/SEAM3D Properties

Rows, columns, or layers can be added or removed from a 3D grid. A row, column, or layer may be added to the grid by using one of the following tools:

• Add_i_Boundary

• Add_j_Boundary

• Add_k_Boundary

The boundary of a cell can also be moved to a new location by using the Move Boundary tool. Existing rows, columns, or layers can be deleted by using the Merge Selected command in the Grid menu.
