Code comments
if initlvl, minlvl, maxlvl are units dependet, why elev is not?
In the EPANET interface, curve-X[0] may not be 0, however it draws a curve. Here, it will be considered as a custom curve. Because?
What if I want to add a head loss curve?
"int DLLEXPORT EN_setflowunits(EN_Project p, int units)" requires curve type to apply unit conversion factors, but curve type is only applied in functions: "int energydata(Project *pr)" sets to EFFIC_CURVE, "int valvedata(Project *pr)" sets to HLOSS_CURVE, "int updatepumpparams(Project *pr, int pumpindex)" sets to PUMP_CURVE, "int valvedata(Project *pr)" sets to HLOSS_CURVE. It is not clear the mechanism of loading an INP file.
Why here, elevation is not converted to feet??
If in EN_setnodevalue, is the value passed converted to feet?
Acredito que aqui deveria ser
elevation = elev / Ucf[ELEV]
I believe that here should be
elevation = elev / Ucf[ELEV]
