I had gone through previous posts but could'nt find the suitable answer. I'm trying to plot Temperature vs Height using Line as reference for my transient analysis. In charts > XY-transient, the data source as a point is only available. Whereas in XY-Line, the datasource as line is available but is confined to single timestep. Any suggestions that how can I plot it across the complete simulation time?

I think you need to have a look at what you are trying to do.

In a transient simulation, if you get data at a point over time - then you have a 2D plot with the data in the y axis and time in the x axis.

In a steady state simulation, if you get data at a line at one point in time - then you have a 2D plot with the data in the y axis and distance along the line in the x axis.

If you have a transient simulation and you are trying to plot a variable over a line you now have 3 dimensions you are trying to plot (distance along line, the variable, time) - so a 2D cartesian plot is not longer suitable. How do you want to plot the third dimension? As a 3D surface? A series of lines? Multiple 2D cartesian plots?

Thank you for explaining. I would like to plot the temperature vs. height as marked in the image across the simulation period of 360s. Could you please explain what I need to do if I want to utilize the lines as a reference?

I do not know of a good way to display this inside ANSYS or CFX. I would export it and use a graphing package like python (with matplotlib), matplot or excel to plot it.

You can automate the exporting of the data using a CFD-Post session file.
