Function Documentation

int DLLEXPORT ENinitH

(

int

initFlag

)

Initializes hydraulic analysis.

Parameters

flag	2-digit flag where 1st (left) digit indicates if link flows should be re-initialized (1) or not (0), and 2nd digit indicates if hydraulic results should be saved to file (1) or not (0).

Returns

Error code

int DLLEXPORT ENopenH

(

)

Sets up data structures for hydraulic analysis.

Returns

Error code

int DLLEXPORT ENrunH

(

long *

currentTime

)

Run a hydraulic solution period.

Parameters

[out]

currentTime

The current simulation time in seconds

Returns

Error or warning code

This function is used in a loop with ENnextH() to run an extended period hydraulic simulation. See ENsolveH() for an example.

int DLLEXPORT ENsaveH

(

)

Saves hydraulic results to binary file.

Returns

Error code

Must be called before ENreport() if no WQ simulation has been made. Should not be called if ENsolveQ() will be used.
