Please can you post an example of what you're after?  The contour data will show the flow results, and may be a better option?

OK, you'll need to review how point and line monitors are set up using Report Definitions and take data from Fluent to generate the plots. 

[Ayushman Srivastava]

I don't find the information you provided helpful. Please elaborate or provide some sources to understand

[Rob]

They're covered in the tutorials, click on Help in Fluent and you should find them.

How to show the coordinate frame as shown in the figure below, i.e., the x-axis and y-axis in the Ansys Post processing?

[Rob]

You can't in Fluent, check Ensight, otherwise you may need to create the scale and then combine the images.

I am using the DPM model to inject the particles. I selected “group type” and “no. of stream= 20.” and my study is “transient”. A micro-shock tube is used, and the driver section is patched with a high-pressure gas and the driven section is patched with a gas at atmospheric pressure. 

 

I am facing a problem: “Whenever I run the simulation at the same condition, in each simulation, the particle velocity at the nozzle exit is different, and the particle is reaching at a different time at the nozzle exit.” 

Also, in each simulation, the message in the console is " the reverse flow on 168 faces of pressure outlet-12." appearing after every time step.

Why is it so?

As I have no idea what the results or convergence look like it's a little difficult to comment. Please look through what you're doing carefully, then ask your question and include sufficient information for someone to have a chance of understanding.
