|Hi Brent,
|Thanks very much for you help. Since I record simulation data every 60
|seconds over a 24 hour period this would create large amount of files. I
| was thinking that, somehow, one could import the file as general array
|format with sequencer stepping through each timestamp data. However, I
|am having difficulty trying to import it as General array format -- I
|don't know how to creat a header file to describe my datafile.
|
|Any examples of header file importing similar datafile would be most
|helpful.
Your data looked ideal for ImportSpreadsheet.
----cut-here----
series var0a var0b var1a var1b
0 1.1 1.2 1.3 1.4
1 2.1 2.2 2.3 2.4
2 3.1 3.2 3.3 3.4

The only catch is that you want to merge adjacent pairs of columns into
(presumably) a single vector value for each variable.
If you don't have too many variables, you can do this manually in a network
by 'Extract'ing "var0a" and "var0b" for example, running these through a
Compute("[a,b]"), and 'Replace'ing the result on the original field using a
new name -- say, "var0". Repeat for other variables.
If you have lots of variables, you can put the above process in a loop using
the ForEachN module. But this quickly gets out of hand. Personally, I
find it simpler to just write the data in DX native format. Then you can
do exactly what you want. And you want something like this:
object "positions" class gridpositions counts 3
origin 0
delta 1
attribute "dep" string "positions"
#
object "connections" class gridconnections counts 3
attribute "element type" string "lines"
attribute "dep" string "connections"
attribute "ref" string "positions"
#
object "series" class array type int rank 0 items 3 data follows
0 1 2
attribute "dep" string "positions"
#
object "var0" class array type float rank 1 shape 2 items 3 data follows
1.1 1.2
2.1 2.2
3.1 3.2
attribute "dep" string "positions"
#
object "my data field" class field
component "positions" value "positions"
component "connections" value "connections"
component "series" value "series"
component "var0" value "var0"
#
end
Use Slice to grab a timestep of the data.
