| Summary | 0001177: pressurized water starts flowing, then stops | ||||
| Description | I have water flowing from a stream down 2 levels, then up one level from there in order to irrigate an area. Initially the water comes up through the hole in the floor, but then after a little bit it stops. Shutting on and off the floodgate at the stream level causes the flow to resume temporarily, but then it shuts off again. | ||||
| Steps To Reproduce | I've got a save file available. Turning on and off the floodgate at the stream level makes it work temporarily. Go to level 140 and pull the left-most lever in the room by itself. | ||||

I can't seem to find a way to attach the save file. |

Upload the file to the Dwarf Fortress File Depot if Footkerchief or Toady ask for it. Although I'm personally tempted to file this under "water pressure behaving badly", which is kind of a given. You're making a U-bend design, though - this was pretty notoriously buggy in the past, see http://magmawiki.com/index.php/40d_Talk:Water for some examples. |

The save might come in handy, yeah. You can upload it here: http://dffd.wimbli.com/ |

Here's a long but relevant story: I had a big underground quarry in one of my forts that I decided to muddy so I would have easy access to some cave trees without the cave threats. While filling it, I overdid it a little and ended up with 3-4/7 deep water in the whole quarry. This quary was on the same level as a brook. I'd dug it there because a large magnetite cluster was visible in the brook wall. The cluster extended across both sides of the brook, so I had dug a passageway under the brook to the other side to get at the magnetite there. To prevent this passageway from flooding completely while I was wetting the quarry, I covered the entrance with some floor hatches. When I'd overfilled the quarry, I decided to take the hatches out, let water fill the passage, and let pressure spread more water out over the other side. I figured I could pump the passage clear later. Since the water was shallow, dwarves went for a swim and dismantled the hatches. Water filled the passageway, but it did not flow out onto the other side of the quarry. The water on the first side was still 3/7 everywhere because the passage was small. Shouldn't pressure have caused the water to rise onto the other side? If so, why didn't it? Is the brook significant? In the real world, the water would not have filled the other area because of the air pressure in that pocket of quarry (there was no other way in but the now water-filled passage). Has toady modeled this behavior too and not told us? small quarry large quarry ########brook############.... #.......<#brook#< #.......<#brook#< #.......<#brook#< (water) #........#brook## ########brook##########,,,, |

I've done a whole battery of tests of fluid mechanics and haven't really seen anything that looks like a change. I'm pretty sure this is the same old 40d oddities, but we will see I guess. |
