Node Name Arrays

Symbolic node names or named points can be constructed as either single points or as an array of points. An array of nodes is useful when creating a polygonal surface with multiple points.

For example, when creating polygonal surfaces using the PY card and PM card containing many points, only the node name can be specified instead of each individual point. Expressions such as A[2*#i+3] can be used to index the array.

A symbolic node name array can be defined in a loop as follows:

!!for #k = 1 to 20
DP P[2*#k+3]
!!next

When using node names, the nodes can be referenced using only P. Single node names can be referenced by indexing the array.
