When users do surge analysis with InfoSurge, H2OSURGE, or H2OMAP Surge, they will change quite a number of hydraulic parameters related to valve operation, pump operation, and surge protection device. The following shows a procedure to compare surge analysis results between different scenarios.
1. Run the surge analysis without a surge tank
when you are prompted for output source name, click OK.
5. Run the surge simulation again, then the default output source “*Active*:Surge” gets updated
6. Select Junction 478, and click and graph it
7. In the current graph, click the Reference Graph button, click the Reference Sources tab, check the Data from Other Output Source(s) option, select the user-defined output source, and click OK twice to view the comparison (see the following two screenshots)
