.neigh files


Blank lines and comments prefixed by `#' may be placed anywhere. Triangles are numbered consecutively, starting from one or zero. Neighbors are indices into the corresponding .ele file. An index of -1 indicates a mesh boundary, and therefore no neighbor. The first neighbor of triangle i is opposite the first corner of triangle i, and so on.

Triangle can produce .neigh files (use the -n switch), but cannot read them.
