This is an introduction of the function to sort nodes and elements according
to the certain rule.
As an example, the figure 1 is an explanation of how to sort irregular
nodes.

 Fig. 1 Before sorting |
At first, select all nodes in the node coordinate table, and then click
the sort button. (Fig. 2)

A setting window like the figure 3 appears.

Input as below in the setting window:
- Select "Use Input Coordinatesystem".
- Select "Cylindrical" as a new coordinate system type.
- Origin of the cylindrical coordinate system should be at the same position
as the global coordinate system of the model.
- Value in X axis of the cylindrical coordinate system should be the same
as that of the global coordinate system (1, 0, 0).
- Value in Y axis of the cylindrical coordinate system should be the same
as that of the global coordinate system (0, 1, 0).
* Z axis of the cylindrical coordinate will be at the same position as
that of the global coordinate system at this point.
- Select "Y-Axis" in Polar Axis.
- Set Sort order as the followings.
- 1st key = h - Ascending
- 2nd key = r - Ascending
- 3rd key = θ - Ascending
This order means that nodes line up
- from lower position at first,
- and then from smaller radius,
- and from position with smaller rotate angle at last.
- Click Apply button to finish the setting (Fig. 4).

Because "Renumber after sorting" is ticked in this example, nodes
will automatically renumbered after sorting.
Elements can also be sorted. Elements include a frame element, a spring
element, a rigid element, an M-φ element, a fiber element, a mesh
element, primitive in mesh element, a cable element, and a dumping element.
