Physical simulation of multiple scenes simultaneously I have created physical simulation of objects after initiating them from random positions. I am generating about 9 scenes and would like to view these simulations simultaneously on a blender screen as 3x3 matrix view of scenes together. I guess I might have to use viewport stuff, but didn't find anything concrete on what I wanted to do.

Any pointer would be of great help.
Thanks in advance!
It's not possible. The active scene (bpy.context.active_scene, I think) is shared by the whole blender session. 

You could within one scene use several viewports without a problem (check the manual, you click and drag from the \\ section in the lower left corner to create a new viewport and set it to '3d view').

If what you want is a final render with a 3x3 matrix you could render them from separate scenes and merge them using the compositor in a new scene (using translations to move them and scale them to put them at different places on screen).
