Hi, I was working on a project which in which i had to measure properties of fluid flow, so we ploting the solution to one field variable every 0.01 sec. But for post processing, I needed to create a video or animation of some sort, is there any way to obtain a .mov or mp4 file of the plots or save all the plots as jpg in a folder, where i can combine them up to make a video
There are probably a lot of utilities for that although ffmpeg may be a good one,
not sure if imagemagick does it or not,
I guess FF supports something like vtk and not sure if those packages have
other means to do that. Personally I’ve always wanted an app-independent
data view like an oscilloscope and had a real crude one a decade or so ago
but the FF ff-glut renewed my interest. Ideally you just write to a fifo and it
displays and saves etc. If anyone knows of a package like that it may
be nice to have.
There are probably a lot of video editor programs out there if you really
want to get fancy though. I just like simple things that integrate well.
Sorry, but i am a newbie to freeFem and am unable to understand the later part of your answer. I would be grateful if you could elaborate it in simpler way.
Thank you
This illustrates post script output,
https://doc.freefem.org/documentation/visualization.html
and you can make file names based on loop variables.
From there it should be a matter of picking utilities.
I guess another option is to use a screen capture utility with plot. This sounds
cumbersome but if you really want to capture the exact screen output
you could make the plot, write to a fifo, and then have another script that
captures the plot ( with pid discovered somehow I guess ) .
I only mention it since I happen to be doing something similar with c++
processing code dumping dofs to files processing and sending bck to FF.
