41110 error code- Can not solve network hydraulic equation

Dear great support team,

While I simulated the water network attached, I had the error 41110 which showed inability to solve the hydraulic equation.

I have the same model with another input and don't have any issues, but when I tried to change different inputs and after push on compute option, I got this error.

I tried to follow the instructions in the forum but couldn't find the solution.

Thanks in advance

  • Hello Mohammed,

    I am seeing the same issue. If I set some of the elements as inactive, I can get the model to computer, but with some invalid results. If you wanted to test this on your machine, go to pipe P-8 and make it all elements downstream of it (which will be to the left of the pipe) inactive. However, there are incorrect hydraulic grade and pressure results nearby. 

    I attempted to make some adjustments to the calculation options, but could not resolve the issue. At this point, I would recommend reviewing the model, including your tank input and pump input. I would also recommend taking a look at this wiki, which will have some other things you can try: Troubleshooting the Network Unbalanced or Cannot solve network hydraulic equations user notification.

    Regards,
