Problem
When using a General Purpose Valve (GPV), Turbine or Orifice-Between-Pipes (orifice) element with the version 2.2 solver (available starting with CONNECT Edition Update 4), the calculated headloss is very large and does not follow the GPV headloss curve.
Solution
This was a known issue (reference # 1007829) with version 10.04.00.108 when using the 2.2 solver version (selected in the calculation options).
This has been fixed for the 2023 release (23.00.00.16) and the fix will be in higher versions as well. For information on upgrading, see:
If you are unable to upgrade and must stay on version 10.04.00.108, a workaround is to select the earlier solver from the Engine Compatibility field in the calculation options (Home > Options), such as WaterGEMS 2.0.012.
