Plotting a Monitered Data vs. Physical Time

SimulatorMaster · June 14, 2021, 08:10

Hello all

Hope you are doing well.

I have conducted a simulation in order to observe turbulence behavior in a tunnel. I have several points to capture velocity data and Monitor field functions to observe parameters such as variance covariance, Field Mean for velocity, Strain Tensors and such.

Now the problem is that I have forgot to implement a point in the region in which I also had to obtain velocity data.

Now I have several Field Means under Monitor section in which I can pull data from without needing to again capture the data for the missing point by re-running the simulation. But I cannot plot all the samples vs physical time which is not available as a scalar function so I tried iterations; however, it only displays the latest solved value(so the Sim. ended at 400k iterations and it shows the result at 400k).

Is there anyway to solve this problem?

Thank you for your time.

Sincerely
Onur

I think star does not keep all the previous values in transient simulations.

What I do is that I make a table with the quantities I want and automatically export it every x amount of timesteps.

However this would mean that you'll have to rerun your simulations

Yes unfortunately it seems that I need to rerun the simulation. Though thanks for the reply!
