Hi Ian, 
I'm sorry I was not clearer before, english is not my main language. I understand the concepts of the fixed eulerian nodes and the ALE part that flows over them, but I was hoping that somehow the software could still output the velocities of eulerian nodes that are "overlapping" with the ALE part at any specific time step. In fact, the software lets you visualize what I want when you hide everything but the ALE part and plot the nodal velocities. 
Let me explain what I am trying to do so you may suggest me a different approach:

1- I'm simulating an explosively formed penetrator (EFP). One of the ALE parts is the formed projectile (the blue mesh in my previous screenshot), and I'm interested in its peak velocity because I have measured experimentaly the value that it should achieve. 
2- I'm trying to optimize the parameters of one of the involved EOS equations to achieve the experimental velocity.

3- I have heard about Optislang, but have never used it (and I'm not familiar with Workbench either), so I was trying to use my own optimization approach using specialized Python libraries. To calculate the "error" or how far from the objective the results are, I need to know the peak velocity of the projectile. This is the reason I was trying to extract the velocities of that specific part programatically.

Hope everything is clear now and thank you very much for your help.
