Simulated means not the real thing, but made to look, sound, or feel like it. Simulated leather, simulated wood, a simulated emergency in training. Factories, film, and computer work use it a lot. The feeling is “we built a stand-in.” Though actually, it is not always a cheat. A simulated flight can save lives; simulated wood on a wall can just be cheaper. Tone depends on the thing: simulated diamonds in an advert may be trying to impress you; simulated combat in the army is practice. It is the -ed form of simulate, used as an adjective. Neutral-to-technical, common on product labels and in training talk. People also say fake or artificial; simulated often sounds a bit more official, as if someone designed the copy on purpose rather than just passing it off.
