Graph ploting of velocity vs time
 
I try to get the graph of pulsing behavior of my rotating propeller. what I have done is create a point surface within the propeller and monitor the changing of the velocity with time steps. I have run my simulation based on the following detail,

Time step size (s): 0.001; Number of time steps: 250

The monitoring just show me a straight line correspond to time. Am I do the wrong thing? If you have such experiences, please share with me. Thanks in advance.

Re: Graph ploting of velocity vs time
 
Maybe it it due to the fact that your time step is so low that you can't see a variation with time.

have you tried with the report type vertex average? or verified it with mass flow rate?

i hope this helps
