And below is the result:
The smoke is confined to the cube.
I'm guessing there are parameters that I need to adjust but I have not made any changes to the default settings since installing Blender.
Any ideas how to fix this issue?
Thanks in advance.
When on loop it appears to extend above the cube occasionally and when I was tinkering with Physics/Behaviour/Density it actually flowed like it should for one cycle. This may have been coincidence as I've not been able to replicate it. Is this an indication that my computer is unable to simulate properly?
