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.)

|''Create Nodestrings''
|align="left"|The ''Create Nodestrings'' tool is used to create node string. Nodestrings are used for operations such as assigning boundary conditions, forcing breaklines into the mesh, and renumbering the mesh. To create a nodestring:
#Click on a node. The node will be highlighted in red and a prompt will be shown in the ''Help Window''.  
#Click on any node to add it to the nodestring. The selected node is also highlighted in red and a solid red line is drawn between the two nodes. Continue adding nodes to the nodestring in this manner.
##Note: For most operations, nodes in the nodestring should be adjacent, but this is not required.
##Press the ''BACKSPACE'' key to backup one node. Press the ''ESC'' key to abort the nodestring creation.
##Double-click a node or press the ''ENTER'' key to end the nodestring creation.
#The ''SHIFT'' and ''CTRL'' keys assist in creating large nodestrings which are made up of adjacent nodes. These can be used after at least one node has been selected and function as follows:
##''SHIFT''. Holding down the ''SHIFT'' key and selecting another node will add to the nodestring all nodes between the two. The path chosen is the shortest distance between the two nodes. This is useful for creating continuity strings which run along a cross section of the mesh.
##''CTRL''. Holding down the ''CTRL'' key and selecting another node will add to the nodestring all nodes on the mesh boundary between the two, going counter clockwise from the first node to the second node. Both nodes must be on the boundary of the mesh or SMS will beep.  
##''CTRL'' + ''SHIFT''. Holding down both the ''CTRL'' and ''SHIFT'' keys and selecting another node will add to the nodestring all nodes on the mesh boundary between the two, going clockwise from the first node to the second node. Both nodes must be on the boundary of the mesh or SMS will beep.

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:Select node icon.bmp 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:SelectElement.bmp 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.)
