Since 2.82 some of the physics systems have undergone some major changes, specifically Fluid (when mantaflow was added). As such, for the site it seems to creates a bit of a mess with some tags because they overlap.
fluid-simulationexcerpt as of this writing:
Questions about the Fluid simulation systems in blender. Blender has two systems for simulating liquids, a SPH (Smoothed Particle Dynamics) system integrated with the particle system, and a Lattice Boltzmann method which can be used create a variety of simulations.
smoke-simulation is actually an old wiki link as of writing this question, which is how this question came up in the first place.
fire no tag wiki
For a user that reads the tag wiki, this would be misleading, so the information should probably be updated.
Per current documentation, fluid simulation includes smoke/ fire and liquid, so wouldn't be surprised if users unknowingly begin to misuse fluid-simulation for both causing future disorganization of questions as time goes on.
Examples of questions that was asked are Both my fire emitter and my domain became 'wireframe', can't see them in render view
The OP is asking about fire, but tagged the question fluid-simulation as well as fire
also,
The OP is asking about smoke but has tagged the question fluid-simulation and smoke-simulation
Finally, these two tag search results here and here show that it is already becoming quite disorganized.
The question
How should these tags be organized? The given information needs to be updated. So while at it, is it a good idea to create a new tag, liquid-simulation and use that for questions specifically about liquid, and use smoke-simulation for specific smoke questions, and then use fluid-simulation or create mantaflow for both of these?
