Run the Wibu-Key License Manager by clicking START | PROGRAMS | WIBU-KEY | Server-Monitor. When the Server-Monitor starts, click the 2nd speed button from the left (with the magnifying glass) to Browse Network. In the left window pane, click on the name of the server (that has the key plugged in) and a list of active users will appear below it. Click on the user that has terminated abnormally, then click the button marked “Cancel User.”
Yes, there is a free demo program available here. The demo is fully working, for a limited number of pipes.
While some shapefiles will successfully load in the background using the Add Map Button within the Backgrounds Menu, shapefiles are not an officially-supported background format. The appearance of shapefiles imported as background images is inconsistent and cannot be controlled. A better option may be to export the shapefile to a CAD format and use the resulting CAD file as the background image. The export to CAD function is available in many GIS mapping programs. Some of the more advanced CAD mapping programs allow the import of shapefiles into CAD format.
Yes, but in separately-licensed software modules. Pipe2016: KYPipe models liquids. Pipe2016: Gas models compressible fluid (vapor).
No. We recommend users model compressible-fluid (vapor) portions of the piping network using the Pipe2016: Gas module and liquid portions with Pipe2016: KYPipe.
Any gas may be modeled.
No. While a Surge calculation is an analysis over time, it simulates a short period of time immediately following a transient event. An EPS analysis looks at volume changes in large storage tanks, domestic demand patterns and pump control over longer periods of times, usually a day or more. Surge can run a baseline steady-state analysis.
You can build the model in Surge. All modules use the same, very intuitive, Pipe2016 graphical user interface (GUI). All models can be built in any of the Pipe2016 modules, e.g., KYPipe, Surge, Gas, Steam, GoFlow and SWMM.
It is not necessary to purchase both. Surge can run a steady-state analysis to determine losses, flow distribution etc. However, the steady-state features are limited to one simulation using the baseline conditions for each analysis. KYPipe is required in order to to run multiple steady-state scenarios and Extended Period Simulations.
Pipe2016: Gas has a tool that provides gas properties for a number of common gases.
Make sure you have the most current version of Pipe2016. Updating to the current version (e.g., 8.0XX) is always free, regardless of which release (e.g., Pipe2012, Pipe2014, Pipe2016 etc.) you’re licensed for, and may solve the problem.
Additionally, under Print Options, select PDF or BMP instead of Printer. When the file is displayed there will be an option to print it. Do not use a PDF printer driver, use the PDF option built into Pipe2016.
|Option 1 – Access to WaterCAD software:
|Option 2 – No access to WaterCAD software.
|EPANET will not accept pipe names or node names longer than 8 characters. WaterCAD has very few restrictions on naming so when you convert the WaterCAD file to EPANET there is an option to use element labels or element IDs. If none of your pipe or node labels exceed the 8-character limit then using the element labels is acceptable. However, if the names exceed 8 characters, the conversion will truncate the names and numerous pipes and nodes will have the same name. Element IDs are assigned numbers. Using them will make the number IDs the pipe or node name in the converted file.|
A Hydropneumatic Tank element has been added to Pipe2016. This sophisticated element includes a pump and control switch so the user only needs to input the low and high pressure operating points and the volume of water supplied between these settings.
Check that your Units Selection is correct in the System Data Menu. If you mean to use gpm but have selected mgd you will get very high losses. Also make sure that the roughness values you input match the head loss equation you are using. For example, if you select Darcy Weisbach for head loss and input 140 for roughness (which is for Hazen Williams) you will get very high losses.
If you are running Google Earth or MultiMon Taskbar or GoToMyPC close it before starting Pipe2016.
The only file that is needed is the .p2k file.
Sometimes Image2PDF doesn’t register properly the first time you use it after reinstalling the software. If this error continues after the initial use, contact Technical Support.
Make sure that the “Use Former Analysis” box in the Analysis Menu is unchecked. This option was created for large systems when less computational ability was available; it stored fewer data points than the current analysis method.
Yes, but the following steps may be required to enable the software to run properly:
- Extract all files
- Copy the setup file to a local drive
- Browse to the location of this file
- Right click on it and select Properties
- Click on the Compatibility Tab
- Check the box which says “Run in compatibility mode for” and select Windows XP Service Pack 2
- Click Apply and Okay
- Rerun the setup application
Open the first model and select the entire system (or the part you want to copy) – use the Group Box or the Group Polygon tool in the Left (vertical) Toolbar to do this. Under Edit (in the Main Menu), select Copy. Close the first model and open up the second model. Under Edit, select Paste. If both models are in the same coordinate system then the first system will be added in the correct location. If not you can drag it to the correct location. Duplicate node/pipe names will be automatically fixed.
KYPipe conducts an analysis by determining the pressure at every node in the system. Sometimes a line may become closed due to a pressure regulating valve closing; a flow reversal in a pump; a control switch operating with a specified system change, etc. When this happens, if the portion of the system is cut off from a fixed-grade node (i.e., is not supplied in any way), then an analysis cannot be conducted on that portion of the system. To avoid this, KYPipe will open the closed element and continue with the analysis. One way to resolve this issue is to create a “dummy” reservoir connected to the system with a very small diameter pipe. This will simulate a supply so the analysis equations may be set up, and usually will not alter the way the system operates.
When the software is in demo mode the following limits apply:
- Surge models 50 pipes, 1 pump, 1 active valve, 50 SDOs, pipe lengths up to 1,500 m (5,000 ft), and pipe diameters of 25 mm, 50 mm, and 100 mm (1 in, 2 in, and 4 in).
- TranSurge models 10 pipes, 1 pump, 1 SDO, 1 active valve, pipe lengths up to 10,000 m (32,500 ft), and pipe diameters of 50 mm, 600 mm, and 900 mm (2 in, 23 in, and 35 in).
- KYPipe models 50 pipes.
- Gas, Steam, GoFlow, & SWMM model 30 pipes.
The demo can be downloaded here.
Please see Dr. Lingireddy’s blog entry on this subject here.
When protecting a pipeline from a pump trip where there is a very rapid pressure drop using even a short time delay in the response of an air valve could allow a significantly larger pressure drop than if this is ignored. Air valve manufacturers do not provide time delay data so the time delay is generally set to 0. Providing for this input allows the user to evaluate the effect of a time delay.
See our Learning Page for both introductory and advanced tutorials, along with links to training opportunities. The initial page shows model-building videos using the KYnetic interface. Sub-pages show model-building videos using the Classic interface, along with webinars covering various topics, and videos sorted by analysis engine (Surge, Gas, Steam, GoFlow, etc.). These provide excellent, user-friendly, classroom-like instruction including basic Pipe2018 GUI functions and on many intermediate and advanced functions and features as well. Once the videos have been viewed and the user has created a small practice model, more detailed questions may be answered with the Online Help file. Search the Contents page or the Index for the topic in question. Technical Support is available to help with any questions that may arise.
The effect of the CV Time (closing time for CV) is generally opposite of the closing time for a control valve. Normally the longer it takes to close the CV the higher the pressure surge. This is because the reverse velocity is larger the longer the CV takes to close. The higher reverse velocity causes a larger pressure spike when the CV fully closes. This is not always the case because other factors are involved. However, a rapid closure for a CV is generally better.
Licensing is perpetual, i.e., it does not expire. Note that we release new versions periodically, to address known issues and sometimes to offer new features. Updating to the current version (e.g., 8.0XX) is always free, regardless of which release (e.g., Pipe2012, Pipe2014, Pipe2016 etc.) you’re licensed for. Users are never required to upgrade to a new release. However, users may choose to upgrade to obtain access to new features not available with version upgrades.
We do occasionally provide leases and other licenses which expire under special arrangement, but the standard form of licensing has no expiration.
