How to setup the Time step animation correctly?

      Hello everyone!


      I calculate a transient flow and I get 200s of flow.


      I create a animation video type time step of this flow, choosen the first to last step (all time steps), but the video have just 5s. Why? What can I have gone wrong? I using the CFD Post...


      Thanks all!

      Have you loaded all the transient solution data files under CFD post? How many time steps do you see under time-step selector?

      Mantovani, please refer to the following screenshot if you're using Timestep Animation





      If you're using Keyframe Animation (the default setting is 24 fps), please refer to the following post:

      Hello Rahul and Vishal, thanks for the greatful help!


      So Rahul, I open again the CFD Post and I used the setting as control by Timestep. Now I use in the same way of screenshot above and set control by time. I stay waiting some minutes for it's run and I see what I get. 


      Thanks one more time!

      So, Now I get the video with the set in the same way of Rahul's screenshot, but equal before the video just have 5s. 


      Below a image of maybe a solution, I have a doubt... And a contour in a sometime of my simulation, ploting vorticity. 



      For this, I used a steady state first with SST k-omega and second LES model. 


      Thanks!

      Mantovani, sorry for the late reply. The attached screenshot would definitely work. CFD-Post has a default setting of 24fps. Rest should be pretty much self-explanatory.
