error 41596

Hello Rahul, 

We would also require dhnwapur.wtg.sqlite file to open the model, since its a database file without which model cannot be opened. 

Also provide us some details about the error you are getting.

Do you receive this error while opening the model or computing or while using any specific tools? Please elaborate.

It appears to be about user notifications you are getting in the model after computing it. Please double click on the notification to see whats wrong with that model element and try to rectify the issue based on details in user notifications. 

i am not able to upload sqlite file here error is occuring

actually i am getting this error for each of my node when computing it 

i am new to the software please help

Hello Rahul, 

Please upload model files using link below. 

Sharing model files.

Here is learning resource guide of WaterGEMS / WaterCAD for your reference, since you are a new user. 

Learning Resource Guide for new users of Bentley WaterGEMS and WaterCAD

i have uploaded the file name is dhnwapur.wtg.sqlite

i have uploaded the file you requsted on the link above dhnwapur.wtg.sqlite

Hello Rahul, 

Thanks for uploading the model files, 

Is this a real project or its tutorial for you to learn WaterGEMS? 

• The reservoir is set to elevation of 1000 m and other junctions are set to 50 m elevations, which doesn't make sense. 
• Pipes connecting reservoir and pump are set to wrong start and stop nodes. E.g pipe starting from reservoir, start node should be reservoir and not pump. 
• Below are disconnected nodes in the model, they are just overlaying and not connected, please correct it.  
• 
• Pump is not required in your model as everything can flow by gravity, if you remove the pump all isolated nodes user notifications are gone. 
• As mentioned earlier, please go through the learning resources, learn videos to understand how WaterGEMS modeling works. 

thanks this solve my problems 

but i have a question why was adding a pump showing all these errors? , when can i add pump then 

and yes its a real project but i didnt have the real elevation so i added randomly

Rahul,

A pump is used when you need to add energy to the system to increase the downstream pressure or pump to a tank at a higher elevation. Sushma noticed that the reservoir water level was much, much higher than all the junction elevations, which suggests that a pump is not needed since the pressure is already very high even with just the reservoir. If the actual node elevations are much lower though, then the pump may be required to keep adequate pressures. Note that you can import elevation data using Terrain Extractor.

As for the errors, as Sushma mentioned, they are due to the pump pointing in the wrong direction (toward the reservoir) and because of some elements that are not physically connected to the model. You can use Network Navigator to locate such elements. I also noticed that the pipe between the reservoir and the pump is very small causing a large headloss, so you may need to correct the diameter.

thank you so much jesse
