Hello,
I am plotting finite element data on 1D/2D/3D unstructured grids with dx.
This data is usually smooth inside each cell/element/connection, often even
continuous throughout the domain (but for generality, I do not want to use
this latter continuity).
For 2D and 3D plotting this works rather good. For plotting of FE
functions depending on only one variable I want to use the Plot module (as
was suggested to me recently on this list) to generate an xy-diagram. I
wrote something like the file
image-data-1d.dx:
object 1 class array type float rank 1 shape 1 items 4 data follows
0.5
0.
1.
0.5
object 2 class array type int rank 1 shape 2 items 2 data follows
3 2
1 0
attribute "element type" string "lines"
attribute "ref" string "positions"
object 4 class array type float rank 0 items 4 data follows
0.125
0.
0.1
0.125
attribute "dep" string "positions"
object "simplex-part" class field
component "positions" value 1
component "connections" value 2
component "data" value 4
end
Unfortunately, when I look at it with
dx -script --> and then
data = Import("image-data-1d.dx");
data = Options(data, "mark", "circle");
xyplot = Plot(data);
camera = AutoCamera(xyplot);
image = Render (xyplot, camera);
Display (image);
I see that a triangle appears instead of the desired graph. I assume that
the connections component in the file is disregarded. Does anyone see,
what is the problem here?
Thank you very much,
Nicolas.
