Geometry

Here you direct the geometry into the Node that you want to read out.

Neighbor to

In this menu you select the element type whose neighbors you want to output. You can choose between the elements Point and Edge. Only when Point is selected, any element type between Points, Edges and Polygons can be selected via the Neighbor Type menu. If Neighbor to Edge is selected, the polygon indices adjacent to the edge are generally output.

Neighbor Type

Here you select the element type to be searched. You can choose between Points, Edges and Polygons. This selection option is only available in conjunction with Neighbor to Point.

Each element of a geometry can be addressed by a unique index number. Therefore, here you define the index number of the point or edge whose neighborhood you want to search for points, edges or polygons, depending on the Neighbor Type. For edges you have to input a pair of point index numbers, a so called Tuple. For edges, pairs of point indices must always be specified, so-called Tuples.
