I have been given a few numerical simulations regarding fluid mixing and have been asked to extract a few parameters from them using C++. Altogether there are about 1000 VTK files per simulation, and there is one simulation per time step, each to be analyzed separately. Regarding the problem itself, as a result of fluid mixing bubbles begin to form in the mixture. I would like to find the position, penetration height, and width of all these bubbles. I am rather new to CFD and scientific computing so I am a bit lost on where to start.
The only coding background I have is rather basic and mostly regarding procedural programming. What comes to mind is a sort of "divide and conquer" approach for locating the bubbles, but I'm not sure if this would be most appropriate. Perhaps I can use the varying densities to find these parameter? Hoping someone can chime in on this.
