Hi, does anybody know how to show the numbers of the elements and/or the
nodes in a finite element grid? I found an example in dx manuals for
structured grids, regarding row- and column- majority numbering, but it's
not clear to me how to do it for unstructured grids. I think I can't use
the majority command for unstructured grids, can I?
I have been trying to fix missing and wrong triangles in a 3D surface
construction by interactively obtaining the coords of their vertices. I
looked at PickPlot.net and PlotLine.net, then added the following to my
network:
{Pick} --- {Inquire ("Is not empty")} --- {<1>Route} --- {<2>Format} ---
{Caption} --- {Collect} --- {Image}
|---------------------------------> {<2>Route}
and the 1st argument of {Format} is "coords = %f". I think the
{Inquire}/{Route} combination is supposed to prevent an error when there is
no Pick component (the 1st time the network is executed) but it doesn't
work the way I've done it. Otherwise, the only problem is that the output
is the coords of the node -- not its array index. I get the array index by
searching the data file for the nearest coords (DX picks the closest
interpolated point on the surface, not the actual point), so it's a pretty
tedious method.
Please let me know if you improve on it.
