Hello,
I am still doing my first steps with OpenDX. Now, I see at least my first 2D
velocity data with those easy to use 'AutoColor', 'Rubbersheet',...
Unfortunately I still have a problem with streamlines.
My import-data have following easy structure
1 1 x x
2 1 x x
3 1 x x
1 2 x x
2 2 x x
3 2 x x
The columns represent the x-, y- coordinates and the u-, v-velocities at those
points.
To read in those data I use following general-file:
file = /home/fab/opendx.dat
grid = 3 x 2
format = ascii
interleaving = field
majority = column
field = locations, field0, field1
structure = 2-vector, scalar, scalar
type = float, float, float
end
To display the velocities with a rubbersheet, I use the modules:
DXLInput, Import, Rubbersheet and Image. That works fine without any further
adjustment.
Then I thought I could do the same to display streamlines, but there I get
following error-message:
Begin Execution
ERROR: Streamline: Bad parameter: data must be a field, multigrid, or
composite field
Does this mean that I have a wrong general-file? If so, am I not able to use
the same general-file for different visualizations?
Greetings!
