You'll have to be more specific about why your dwarves aren't working. I serious doubt this utility will help, it's probably more a matter of knowing how to make steel.
not a modded game as far as the dwarfs are concerned (only modification is adding a non dwarf civ). i turned on to smelt or make ash for every non fisher or hunter dwarf both manually in game and through the other job assigning utility therapist. i figured this utility would force actions/jobs.
edit: had logs and the ore coal thing that makes 2 net more fuel then correct iron ore and as i mentioned proper skills and labors.
Here's what you've said you have so far:
Logs
Bituminous Coal
Iron Ore
Smelter
Dwarves tasked to smelt.
Here's what you need to smelt iron:
Fuel: Charcoal
made from the logs at a Wood Furnace OR Coke made from your Bituminous Coal/Lignite at a Smelter OR at least 4/7 Magma beneath a Magma Furnace.
Materials: Iron Ore
Workers: Dwarves tasked with woodburning (if you need to make charcoal from logs) AND Dwarves tasked with Furnace Operating
From what you've said so far, your problem may be that you need a dwarf to burn your logs down into charcoal at a wood furnace to get your process started. Once you have one piece of charcoal, you can use it to start converting Bituminous Coal into Coke, which will proceed to fuel your smelting industry for as long as supplies last. Once you're out of coke, though, you'll need to keep chopping down a lot of trees... or go find yourself some magma. It should be noted that, if you want to make
steel, you will still need charcoal/coke even if you have a magma furnace, as well as some flux material.
Also, your problem appears to be outside the scope of this thread. The General Questions forum may be a better source of information regarding gameplay mechanics.
