BUG 4615 describes incorrect application of pump scaling factors to the pump curve gradient, affecting all scaling options and causing errors in the noniterative transient solver. The issue first appeared in version 8.15.0.5062 and was fixed in 2023 Release Update 1 (8.15.1). No workaround exists besides using the pump scaling laws option.
ERROR INFORMATION
Bugzilla Error Number | BUG 4615 |
Description of Error | The pump scaling factors are not applied correctly to the gradient of the pump curve for all scaling options. |
Comments | The pump speed scaling factor and reference density were always applied to the slope of the variable pump characteristic, irrespective of the scaling options selected. This results in incorrect results for the noniterative transient solver. |
First Incorrect Version | 8.15.0.5062 | Corrected Version | 2023 Release Update 1 (8.15.1) |
Workaround Description: Other than using the pump scaling laws option, there is no known workaround. |
