The following tools are active in the dynamic portion of the Tool Palette whenever the Curvilinear Grid Module is active. Only one tool is active at any given time. The action that takes place when the user clicks in the Graphics Window with the cursor depends on the current tool. The table below describes the tools in the Curvilinear Grid tool palette.

Tool Tool Name Description Right Click Menu
File:Tool SelectVertices.GIF Select Curvilinear Grid Node The Select Curvilinear Grid Node tool is used to manually select and edit an individual node location. Currently, the only reason to select a grid node is to adjust the shape of the adjacent (4) elements. The status bar at the bottom of the screen displays the i, j, and id of the selected node. The current position of the node is displayed in the edit fields at the top of the screen. (Dragging of curvilinear grid nodes was added for SMS 11.2.) N/A
File:SMS CGrid Select Cell Tool Icon.bmp Select Cell The Select Cell tool is used to select a grid cell. A single cell is selected by clicking on it. A second cell can be added to the selection list by holding the SHIFT key while selecting it. Multiple cells can be selected at once by dragging a box around them. A selected cell can be de-selected by holding the SHIFT key as it is clicked.

When a single cell is selected, its Z coordinate is shown in the Edit Window. The Z coordinates can be changed by typing in the edit field, which updates the depth function. If multiple cells are selected, the Z Coordinate field in the Edit Window shows the average depth of all selected cells. If this value is changed, the new value will be assigned to all selected points.

With one cell selected, the Edit Window shows the point i,j location. With multiple cells selected, the Edit Window shows the number of selected cells. The number and size of the cells can be changed in the Model Control.

When one or more curvilinear grid cells are selected, a right-click in the graphic window will bring up a menu. The menu has the following commands:
  • Delete – this will delete the selected cell(s).
  • Set Observation Station – this will bring up the Observation Station dialog.
File:SelectMeshElement.gif Select Cell The Select Cell tool is used to select a cell (or element) of a curvilinear grid. Currently, the only reason to select a cell is to delete it from the grid and create a hole (or notch) in the grid. This would be done when the cell covers an island or other region that should be excluded from the computational domain. The status bar at the bottom of the screen displays the i, j, and id of the selected cell as well as the area of the cell. (Deleting of curvilinear grid cells was added for SMS 11.2.)
File:SelectMeshNodestring.bmp Select Nodestrings The Select Nodestrings tool is used to select nodestrings. Nodestrings currently serve no purpose for curvilinear grids.
File:CreateMeshNodestring.JPG Create Nodestrings The Create Nodestrings tool is used to create node string. Nodestrings currently serve no purpose for curvilinear grids. N/A
File:SMS CGrid Split Grid Column Tool Icon.bmp Split Grid Column Inserts a new column into an existing grid. This tool splits an existing column into two columns at the location selected by the user. N/A
File:SMS CGrid Split Grid Row Tool Icon.bmp Split Grid Row Inserts a new row into an existing grid. This tool splits an existing row into two rows at the location selected by the user. N/A
