Changelog
25.03.1
06.03.2025
1. The calculation of ring networks has been slightly improved.
2. Now font size of the object labels can be changed in the settings window.
3. fix: previously, when changing an object, the properties table on the bottom left was not updated. Now it is being updated.
25.02.1
03.02.2025
1. Added calculations of λ (friction factor) according to SP 399.1325800.2018 (adj. A) and according to the Colebrook-White formula.
Previously, the calculation was always carried out using the formulas from SP 42-101-2003, p.3.28, now there is a choice.
n>
2. Added a setting for accounting for changes in ambient air pressure in the calculation of ∆PZ.
Previously, the density of air was always subtracted from the density of the pumped fluid.
3. Air has been added to the list of parameters of the pumped fluid.
4. Added object search by id – Ctrl+G.
5. fix: fixed an error in automatic diameter selection, which in some cases could cause excessive narrowing of the most recent sections (closest to the consumer).
6. fix: the selection of the background image has been fixed (previously, after selecting the file, Stocks did not release it).
7. The size of the workspace and max mismatch have been added to the statusbar.
8. The parameters ∆P for splitters and Qmax for sources, pumps, and reductors are marked as obsolete.
24.09.2
26.09.2024
fix: error in automatic diameter selection in schemes with reductors or pumps.
24.09.1
18.09.2024
1.
Automatic pipe length depending on the distance between the nodes of the beginning and end of the pipe.
The scale of the entire circuit can be recalculated by the known length of one of the pipes.
It is also possible to set a fixed pipe length that does not depend on the position of the nodes.
2. Columns with the names of the start and end nodes have been added to the pipe table.
3. fix: in rare cases, there was a loop during the calculation.
4. When selecting several pipes, their total length is shown in the table on the left-bottom.
5. The installer now installs in Program Files, not in AppData.
Old versions of Stokes don't know anything about the automatic length recalculation parameter. Therefore, if you open in older versions a file with automatic length pipes created in the new version, then when saving all pipes, the length will be fixed.
24.03.1
01.03.2024
Added export to PNG.
fix: the calculation crushed if the sources of the subnet were 2+ pumps or reductors
24.01.2
26.01.2024
fix: when adding a splitter, if there are previously deleted objects in the cache of old objects, the added splitter had ∆P = 500 Pa instead of 0.
24.01.1
12.01.2024
The release version of a large package of improvements. For a list of improvements, see the description of previous beta versions.
+Fixed rare bugs that remained in the previous beta version.
23.12.1
beta
15.12.2023
1. The automatic diameter selection is now made in a new window with the ability to adjust some parameters. You can also set your own list of diameters, among which the computer can choose.
2. fix: fixed an error with opening files introduced in the previous version.
23.10.1
beta
11.10.2023
1. Calculations and Ctrl+Z have been significantly accelerated when a large number (500+) objects in the scheme.
2. fix: Ctrl+Z might not work correctly if the previous one did not have time to calculate before the next action.
3. fix: Sometimes pipes were accidentally added when dragging the scheme with the middle button.
4. fix: the center was shifted if there was an object under the cursor at the time of the zoom.
5. Water at 10°C has been added to the drop-down list of pumped fluids.
6. In the table on the left-bottom, the sum of consumptions of all selected consumers is displayed.
For item 1, it was necessary to significantly rewrite the reader and rendering. The automatic diameter selection has not yet been adapted to the new calculations. If you need it, use the previous version for now.
22.12.1
01.12.2022
1. Performance improvement with a large number (500+) of objects in the scheme (only Ctrl+Z has remained slow).
2. Mass edit of objects (F2 button).
3. Customizing object labels (in the settings – F12) and turning them on/off (F7).
4. Ctrl+X, Ctrl+C, Ctrl+V. Please note: only those pipes that are selected along with both nodes are copied. If only one of the nodes is selected, it will be copied without a pipe.
5. Selecting objects with Ctrl or Shift pressed.
6. A new checkbox in the scheme resize window (Ctrl+R), which allows you to proportionally stretch/shrink the workspace and objects. This should be very useful when there are already 200-300 objects in the scheme, and then it became clear that it was somehow cramped, the inscriptions on each other they get into each other, etc.
7. Added "Print (for PDF printer)", which improves export to PDF using the built-in Win10 PDF printer.
8. kPa is added.
9. Steel pipes up to 65mm in the drop-down list have been replaced with pipes according to GOST 3262-75.
10. Various minor bugs have also been fixed.
22.07.1
04.07.2022
Interface improvements, bug fixes.
Added English, feet, inches.
Using feet, inches and gallons in the 21st century is barbaric! At the moment, only 3 countries out of 200+ have not switched to meters and kilograms: Liberia, Myanmar and some other country... If your customer asks for feet and inches in project, be sure to increase the price of the work :)
22.06.1
14.06.2022
Added arrows showing the direction of the flow.
Updated the reference: added PE pipes SDR 11, SDR17 and SDR21 from GOST 18599-2001.
Minor bugs have been fixed.

02.05.2021
A few minor changes:
1. Zoom just with the mouse wheel (without Ctrl).
2. Now you can drag the workspace by holding down the mouse wheel.
