The simplest would be to have a separate file for each time step structured
in the same way, e.g., tech3d_sum-001.dat, tech3d-sum-002.dat, ...
Then connect Sequencer->Format->Import, using Format to construct the file
name. In Import, you can put the entire general array format specification
without having a .general file, i.e.,
Import(,,format="general, grid=82x50x66, format=ascii, ...")
There are several ways to make this more efficient, including using binary
data and doing an initial Import of just the grid and have the subsequent
time steps just read in the data and Replace them, assuming the grid is
time invariant.

Hi all,

I have no problem making miff-files with WriteImage, but my problem
is getting to know DX that I have more data than just one time step. Right
now
I use a 'general'-file with Import to get the data to DX; it looks like
this:
file =
/home/fab/HOME/Dissertation/simulation_calc/16/OpenDX/tec3D_sum.dat
grid = 82 x 50 x 66
format = ascii
interleaving = field
majority = column
field = locations, uvw, p
structure = 3-vector, 3-vector, scalar
type = float, float, float
end
So I have inside the data-file 'tec3D_sum.dat' the locations and one time
step
data which are in line with the according locations.
Would it be possible to add the data of the next time steps in the next
columns? 'field' and 'structure' would look like this:
field = locations, uvw, p , uvw, p , uvw, p , uvw, p , uvw, p , uvw, p ,
uvw, p , uvw, p ...
structure = 3-vector, 3-vector, scalar , 3-vector, scalar , 3-vector,
scalar , 3-vector, scalar , 3-vector, scalar ...
That looks to much; especially when I have a couple thousand time steps. Is
there a different format more suitable than the 'general'-file?
Best Greetings!
