Hello 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 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

surf(x,z,U_sol)
F=getframe;

x and 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 plots like a movie.

On top of that 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.

 close (writerObj)

and you will have the movie file without dealing with each frame. There should be some equivalent version in Mathematica. Thank you for the help.

and Happy New Year :)
