I am going to develop an unsteady diffusion calculation in Mathematica. Because it is unsteady, I would like to visualize the solution each time step (or in some time steps). My MATLAB skills are much better than Mathematica, so I am going to give the example from there. I looked at some of the posts about that, but they were for small number of time steps like 10, or saving each plot and creating a movie. But in MATLAB I can do
z are the position vectors and
U_sol is the solution matrix.
GetFrame simply preserves frame but not the plot, so it looks like a continuous plotting, like a movie.
In Matlab, you can do something like this to save the movie directly. This is before time steps
fid=figure; pos=get(fid,'position'); writerObj=VideoWriter('sol.avi'); writerObj.FrameRate=10; open(writerObj);
and inside the time loop
PLOT... frame=getframe(gcf); writeVideo(writerObj,frame)
and at the end of the time loop.
and you will have the movie file without dealing with each frame. There should be some equivalent version in Mathematica.
