GASWorkS has continued to evolve since Bradley B. Bean, PE first quite simple but effective version of the software was released in 1991. Bradley B. Bean, PE latest release sports a very sophisticated map style graphical data interface, a quick solution routine, and provides support for a number of different model elements, including support for individual customer features. GASWorkS provides an extensive set of network modeling tools designed to assist the User analyze and design distribution, transmission, gathering, and plant piping systems conveying natural gas or other compressible fluids.

GASWorkS may be used to create steady-state models of systems containing not only standard pipe type elements, but also supports regulator, compressor, valve, well, and fitting type elements. GASWorkS calculates the estimated valve coefficient for regulators, and the estimated power and fuel requirements for compressors. A pipe sizing function is provided to assist in determining the required size for selected pipes in the model.

The Graphical Data Interface...
The Graphical Data Interface (GDI) provides map style graphical access to the model data. The GDI allows the inclusion of bitmap (BMP), Drawing Interchange File (DXF), or Shape (SHP) files as a reference background. Using the GDI, the User can draw the model schematic using point-and-click mouse entry, coordinate value entry, or relative distance and angle entry. The GDI provides pop-up data screens for editing and viewing of the various pipe, node and customer data and analysis results.
The GDI includes a wide variety of tools for modifying the pipe, node, and customer model features including routines for adding, deleting and moving features - and the ability to undo accidental changes and deletions. Three independent display panels support various zoom commands including the ability to zoom in by a User specified window, zoom by a User specified scale, and zoom to a previous view allow the User to easily move around the model image. A robust set of color coding and tracing routines enhance the User’s ability to graphically review the analysis results and the system’s performance. The trace routines are complimented by the inclusion of what we refer to as “attribute” valves. The attribute valve feature was developed to assist in the design and layout of emergency isolation areas. A complete set of annotation routines allows the User to include notes and references in the model
graphics.
The GDI display can include: Two-point, polyline, and arc style pipe symbols • Node, customer, and pseudo service line symbols • Pipe, node, and customer data values as text • Piping symbols for non-pipe type elements • User defined annotation, graphic lines and shapes • Attribute (isolation) style valves • Flow direction arrows • Marker Flags • And multiple background reference images. The User may customize the GDI's display properties by setting display colors, line and symbol types, and display size and width.
The GDI tools are accessed through descriptive tool icons contained on function based “fly-out” tool bars, through a command line and list interface, and through a floating tool palette which can be arranged, sized, and placed to meet the User's preference.

The Report Routines...
The report routines provide spreadsheet style reporting of the model data, attribute data, and analysis results - including the ability to edit data directly
from within the report by simply selecting the cell you wish to edit and making the desired change. The User may select the items to be included in the report by collapsing the columns associated with the unwanted items.
The pipe report provides a comprehensive collection of information including reporting of both size/type and internal diameter values, reporting
of pipe inlet, outlet and average pressures, flow rates, velocities and volumes, and simultaneous reporting of linear and pressure drop per User specified length. Selection sets may be created from within the standard reports, allowing unique reporting of User specified data groups. Hierarchical queries allow the creation of sub-sets from a previously created selection set.
Reports may be printed onto any W indows supported device, allowing the selection of paper orientation, and font size and type. Pipe, node, and customer can be viewed using the “standard” spreadsheet style report - summary, data error, solution log and exception reports are also provide. Customer reports may be created by exporting the model data to a third party database, spreadsheet, or word processor application.

Other Features...
Import And Export Routines: GASWorkS includes an extensive set of import and export routines allowing data to be exchanged between a variety of applications. Support is provided for ASCII, DBF, Microsoft Access and Excel data files, third party model data files, Arc/Info shape (SHP) files, and a robust DXF translator allowing both import and export of graphical data.
The DXF and SHP import routines allow the automated creation of a GASWorkS model from a CAD drawing or GIS data set. “Quick Export” routines are provided to allow export of complete model data with a single click.
Customer Features: Diversified load values for antenna or looped type network configurations can be automatically distributed using the Diversity
handling features - based on the British IGE calculation standards. An external database may be attached to the GASWorkS customer data features. This is especially useful for connecting the billing file data to the model data.
Main Attribute Features: An external database may be attached to the GASWorkS pipe data features. This is useful for maintaining the non-model attribute data such as address, pipe specification, test pressure and MAOP values.
User Interface: Each of the GASWorkS routines are accessed through its friendly and efficient point-and-click User interface. GASWorkS is fully menu-driven and provides logical data entry screens and dialog boxes which guide the User through the required entry. On-line help, including an extensive collection of how-to topics is just a click away.
