Hello, its hard to tell if the curves are matching or not as the scale range of flow time axis are not same in both the graphs. However, looking at the images, it seems like they are similar.
To get the animation sequences under animation playback, you have to set the solution animations before running the calculation. To do so, you can go to the Solution Tab of Ansys Fluent ribbon, then under Activities group, click on create drop down menu and select solution animations. Then, set the animation by defining different values and selecting animation object. Once done, run the calculation and after the solution completes, you will see the defined sequences under the playback option.
To know more about how to define solution animations, please check the link of a section of Ansys Fluent User Guide given below.
