Do you need to run a closed zone system curve analysis in InfoWater Pro?

Occassionally, our support team will hear from customers who are sizing a pump for replacement in InfoWater Pro who have run into an issue when performing a system curve analysis. They receive this error message: “Simulation failed with specific issue(s).”

Error message you’ll see when there is no tank on the discharge side.

When this happens, they’ve run into an edge case in our software. If you are running a system curve analysis to determine energy usage and capturing the highest and lowest system curve possibilities but there is no limit to the outflow – if there is no tank on the discharge side – you may encounter this error message.

But fear not. There is a way to compute it.

Instead of using the automated tool inside the software, you will need to compute it manually. First, download this Excel spreadsheet. Then, follow along in the walkthrough video below.
