Monkey won't smoke or burn I've just started with Blender, following Blender Guru's beginner tutorial lesson 1.
I can get the monkey mesh and the smoke box but when I click "play" nothing happens. The monkey won't burn either.
I've tried selecting the monkey and not the smoke, the smoke and not the monkey, both of them and neither. None of it makes a difference.
Blender version 2.82.7
How can I get Blender to do what it ought to?
In Blender 2.82, the fluids simulation system has been replaced by Mantaflow which default's caching methods, "modular" doesn't bake on playback. It instead allows you to bake different settings of your simulation individually, which saves a lot of time when you're tweaking your simulation.
You have to manually start the baking via the domain's panel. You can also change the caching method, but honestly the new "modular" is usually a better option).

I'd suggest you follow tutorials specifically made for Blender ≥2.82 or with "mantaflow" specified in the title.
