Hello everyone.
I have User User notification message id 41891 with my hidraulic model .
Please help me to resolve that. Tnaks all

Hello Humberto,
Only the .wtg file is included. Please go to File > Save to Package to create a zip file with the files we need. This link has information on getting the files over to us: Sharing Hydraulic Model Files on the OpenFlows
Regards,
Scott
I believe error 41891 is "Pressures below the lowest physically possible" (please confirm). If so, this message is telling you that the pressure somewhere in your network is not only below zero, but below the vapor pressure limit and therefore the results are not valid. Please see the following article for help on troubleshooting negative pressures: Troubleshooting negative pressures at pumps, junctions, & other node elements
If this does not help, please provide the complete set of model files as Scott mentioned, plus details on the message you are seeing and any other specific steps to reproduce.

I would recommend reviewing the link Jesse provided for information on this issue. However, I believe that the issue may be related to the pipe diameters. The diameters of all pipes in the model is only 29.4 mm. This can lead to a large headloss in pipes with significant flow. For instance, pipe RED AP (Polyline)-29 has over 50 meters of headloss there alone. This will add up as you move downstream, leading to pressures well below zero.
Based on this, I would make sure that your pipe diameters are accurate.
