My main reason for wanting to learn how to use OpenDX is to view the results
of a family of finite element models that I use (hydrodynamics and water
quality). The models use a mixture of element shapes, which means that in
the 2D case I can describe the modelled region with triangles, and in the 3D
case with tetrahedra. I have been trying to find out what I can do in the
way of viewing 3D results, using a trivial test case:
object "tetra connection list" class array type int rank 1 shape 4 items 1
data follows
0 1 2 3
attribute "element type" string "tetrahedra"
attribute "ref" string "positions"
object "position list" class array type float rank 1 shape 3 items 4 data
follows
0. 0. 0.
100. 0. 0.
0. 100. 0.
0. 0. 100.
object "conc list" class array type float rank 1 shape 1 items 4 data
follows
1.
2.
3.
10.
attribute "dep" string "positions"
object "conc_data" class field
component "positions" "position list"
component "connections" "tetra connection list"
component "conc" "conc list"
end
I have tried using slice and slab, but these don't work with irregular
connections. Other things I have tried, like Import>Mark>Isosurface>Image,
don't give me an error, but produce no image. I hope I am overlooking
something here, otherwise OpenDX isn't going to help me much. Is there a
way to look at data with irregular 3D connections?
