Hello everyone I would like to know if there is a way to edit a video from images like freefem++ does when we display the solution of an evolution equation at each moment. For example I solve a heat equation and with plot I display the solution u(x,y) at each time t. I would like to know if there is a way to record the images directly and how I can read them simultaneously one after the other. Thank you for helping me. ---

You should use ParaView for that. ---

How to store with savevtk u(t,x,y) in block to be able to read it with paraview. that is to say store u at each time t but in the same .VTU file ---

Hello, I did not find a solution within FreeFEM, I did something like that by: - transferring to python with pyfreefem (does not work on windows) - displaying with matplotlib while storing in an image buffer - using opencv to generate a video from the images ---

> I did not find a solution within FreeFEM There is one, and I just gave a link above. It’s also explained here [https://www.youtube.com/watch?v=-Aw2O46V2bo&t=6800s](https://www.youtube.com/watch?v=-Aw2O46V2bo&t=6800s) (it works the same whether you are using things in parallel or not). ---

AFAICT, there are a lot of ways to make movies with a series of slides but if you want to watch in real time, the FF plots are ok but limited and specific to FF. I’ve finally gotten around to making something I call mjmdatascope which is designed mostly to monitor progress from a variety of sources ( interfaces now for FF,R, and c++ code ) and save images or movies. Right now I just have 1D FF but eventually will add more stuff. If you can’t find a solution you could look at this and make suggestions for priorities. I’ve got a couple examples up there including a recent movie of 2D sim that is jerky but fixing that 🙂 [mjmdatascope](https://github.com/mmarchywka/mjmdatascope) ---

It’s very interesting. Thank you very much and happy new year.
