To bring up the MeshTool, select
Main Menu > Preprocessor > Meshing > MeshTool
The MeshTool is used to control and generate the mesh.
...
We'll now specify the element type, real constant set and material property set to be used in the meshing. Since we have only one of each, we can assign them to the entire geometry using the Global option under Element Attributes.
Make sure Global is selected under Element Attributes and click on Set.
This brings up the Meshing Attributes menu. You will see that the correct element type, material number and real constant set are already selected since we have only one of each.
Click OK. ANSYS now knows what element type (and associated constants) and material type to use for the mesh.
...
Since a LINK1 element is equivalent to a truss member, we will specify that we want only one element per line. This is a subtle point and also very unusual; in most problems, you want to subdivide your part into many elements.
In the MeshTool, under Size Controls and Lines , click Set.
In the pick menu that comes up, click Pick All (since we want the specification of mesh size to apply to all lines in the geometry). This brings up the Element Sizes on Picked Lines menu. Specify No. of element divisions to be 1. Click OK*. * ANSYS will now use 1 element to mesh each line.
...
In the MeshTool, make sure Lines is selected in the drop-down list next to Mesh. This means the geometry components to be meshed are lines (as opposed to areas or volumes, as we'll see later). Click on the Mesh button.
This brings up the pick menu. Since we want to mesh all lines, click on Pick All. The lines have been meshed. This is reported in the Output Window (usually hiding behind the Graphics Window):
...
Close the MeshTool.
View Element List
Utility Menu > List > Elements > Nodes + Attributes
This table says that Element 1 is of material type 1 and element type 1 and is attached to nodes 1 and 2 and so on. In this element list, the order of the two nodes for each element doesn't matter. For example, element 3 can be attached to nodes 2 and 3 or equivalently, nodes 3 and 2. Also, the order of element numbering is not important since it is for internal bookkeeping.
...
In order to see where the nodes are located, you can look at the list of nodes.
Utility Menu > List > Nodes
In Sort NODE Listing menu, click OK to accept defaults.
My list of nodes looks like this:
