Description

Create a pump for the water hammer scenario using the method of characteristics. This feature allows you to add a specific pump to the simulation scenario, defining its main characteristics such as operation curves, efficiency, and installation conditions. It is particularly useful for simulating pump behavior under hydraulic transient conditions.
