Need help loading transient data from a single Tecplot file
 
I want to read transient data from a single .plt file as shown below:

Code:
VARIABLES = "X", "Y", "Z", "U", "V", "W","FX", "FY", "FZ"

When I read this file Tecplot reads it as multiple zone. This is meant to be one zone containing data from multiple time instances. How can I do that in Tecplot with a single file?

Hello Nikolaos,
It looks like you have 3D data here--how are you wanting to view this data? Do you want to see all the points all at once or one time step at a time and move from one solution time to the next? If you want one time step at a time, then multiple zones is required (at least one zone per solution time). Also, just for clarity, the .plt is a binary file format--this looks like ascii format, so you can save the data file with a .dat extension.

I want to see the data one time step at a time. I think I was able to read them and view them in 2D mode, but in XY plot I can't animate in time. Yes, this is indeed an ASCII file and it can be .dat file extension.

The XY Line mode doesn't allow stepping through multiple time steps--that is only available via 2D or 3D Cartesian mode. You can plot a similar line in 2D mode by turning on the mesh layer if you want to visualize each plot per time step.
