Dwarf fortress water pressure

Dwarf Fortress features some pretty complex behavior in an attempt to simulate fluid mechanics. One aspect of this behavior is seen in the form of pressure.

There are several mechanisms at work that try to simulate water pressure in game. While on the whole amazingly accurate, there are several unexpected quirks concerning speed and displacement. Never think you are on the safe side, especially when trying to trick the game. A technical explanation by Kanddak from the Bay12 Forum outlines in detail what is known of the in-game fluid mechanics from player testing. Dwarf Fortress attempts to replicate hydrostatic water pressure.

If I have a river on Z 10 as my water source, and my well on level Z 5, with my reservoir on Z 4, can I use the diagonal block method to bring my water pressure down to Z 4 without it flooding it's way back up to Z 5? I know a U bend will only drop you one level from the source. Showing 1 - 2 of 2 comments. Though I don't know the exact answer to your water pressure question, I do know you can always just use floodgates and levers if you're worried about water pressure to create an 'airlock' system on a central cistern which can't overflow. Yes, when water squeezes through the diagonal square it is considered a different water source. I found this video answered a lot of my water questions. Per page: 15 30 Date Posted: 30 Dec, pm.

Wells are buildings that provide access to a water source for your dwarves. A well can be an important feature of a fortress, providing a clean and usually safe water supply compared to rivers , pools and cavern lakes. However, getting water from a well will neither clean nor desalinate it, so you still should make sure that the well has access to clean water. Wells provide an emergency drinking source in case the alcohol runs out don't let that happen! A well is a water source that if constructed correctly will not freeze in the coldest weather, and should last in hot. Enemies that can swim can and will path into your fort through a well. Grates can block underwater threats, but be warned: they cannot stop building destroyers which approach from below. A well constructed above-ground, even indoors, will not prevent the water tile beneath it from freezing. When this happens, the "empty space" requirement for the well is no longer met as the space is occupied by the ice, and the well will be dismantled into its original components Prevent this by placing it one Z-level above the water source if it freezes.

Dwarf Fortress features some pretty complex behavior in an attempt to simulate fluid mechanics. One aspect of this behavior is seen in the form of pressure. The basic idea here is quite simple - certain forms of fluids movement exert pressure , causing them to potentially move upwards into other areas.

This does not work on a vertical basis - water only travels straight up and down to different Z-levels, never diagonally. Namespaces 40d Discussion. Per page: 15 30 Water can only flow straight upward, not up and to the side at the same time. See here for more details on the new versioning policy. How can I divert a river to allow safe ish indoor fishing? View mobile website. Pressure will not propagate through diagonal gaps. There are three methods for neutralizing fluid pressure: diagonal connections, screw pumps, and active control systems. If you wish to maintain the rate of flow after de-pressurizing, it's recommended that you have more diagonals than water tiles - that is, if the source is 3-tiles wide, you may wish 4 or more diagonal passages.

Knowing how to manipulate pressure as needed allows you to quickly move fluids wherever you wish in your fortress allowing you to build things a dwarf can be proud of. When a liquid is moved or created with pressure, it attempts to locate the nearest tile on the same Z-level as its destination tile for falling water, this is 1 Z-level beneath its original location by moving north, south, east, west, down, or up. In this case, since it no longer has a "preferred" area to flow into, the pressure exerted by the river source highlighted in red allows the water to fill up the remaining level of the u-bend. In this case, the river is free to flow off the edge of the map, so the only pressure comes from the water tile on the top of the u-bend's left side highlighted in green falling downward into the tile highlighted in red , so the water on the right side stops one level below the river itself, because even though the source tile is at river level, the destination tile in red , whose height the water will reach because of pressure, is one z-level below the source tile. Obviously the game treats water connected only by a diagonal tile as not connected in terms of "pressure" but only in terms of "diffusion". Views Read Edit View history. If you wish to maintain the rate of flow after de-pressurizing, it's recommended that you have more diagonals than water tiles - that is, if the source is 3-tiles wide, you may wish 4 or more diagonal passages. For lower levels simply continue alternating the -1 and -2 layouts. The control system is designed to only open one of the doors at a time. Use this page to report any issues related to the migration. I found this video answered a lot of my water questions. Different from the above, a river that pushes water into a tunnel system will fill it up to the z-level of the river itself, but not higher again, unless only connected by diagonal flow, see below. Dwarf Fortress features some pretty complex behavior in an attempt to simulate fluid mechanics. By understanding how pressure works in a u-bend you should be able to adapt this knowledge to use fluids in any configuration you desire without any unexpected surprises that could make life in your fortress more fun than anticipated.
