I have an in-line pumping system and I wanted to simulate the pump start-up , I set the problem as in the various examples present in the comunity, but the result of the analysis is "wave speed must be greater than zero".
What could be the problem? thank you for the answer.S.Nicolaprogettoaccensionepompe.wtg

Hello Giovanni,
You have not specified wave speed for pipes in transient properties. For HAMMER to complete the transient calculations, the wave speed of the pipe must be entered.
Below are ways to enter wave speed for pipes and theory behind it, please go through it.

Also here is technote on modeling pump start - up event for your reference.
