How can I get the velocity in the x,y and z directions

The results of my date doesn't have the velocity in different directions. How can I get them or read them in tecplot.

Have you checked the documentation:

I have read it. But the available volume output fields for the comp. fluid doesn't have VELOCITY-X or VELOCITY-Y. Can I get its data?

Did you use the compressible solver?

For compressible flows, the momentum is stored instead of the velocity. You will need to divide this by density to get velocity.

Yes, thanks a lot.
