3. Pendulo kernel library (penwin32.dll)

4. valid Pendulo_size and Pendulo_version license

This tool expects Picwin32.dll to be in the PATH or in one of the following folders:

                %localappdata%/Programs/Safege/Pendulo or
                %localappdata%/Programs/Suez/Pendulo or

With custom installations, PENDULO_DIR environment variable can be set to define the path.

Content

The package provides:

1. pen_vers = init(debug=0) function

2. close() function

3. vdat, vval = ts(id_elem, typelt, attr) retrieves the result TS for element ‘id_elem’ of type ‘typelt’ and attribute ‘attr’.

Example of ‘typelt’ and ‘attr’:

1. ‘LINK’ or ‘ARC’: ‘Q’

2. ‘NODE’ or ‘NOEUD’: ‘P’, ‘CH’ or ‘HH’

3. ‘TANK’ or ‘RESERVOIR’: ‘NC’ or ‘NV’, ‘VO’

4. ‘PUMP’ or ‘POMPE’: ‘PC’, ‘VR’, ‘Q’
