Functionality is no longer enough. Your fluid handling systems must be cost and energy efficient while providing a high degree of operability and reliability, tightly integrated with other systems. The days of analysing line by line are past. Meeting today’s challenges requires a systems approach to your design. AFT FathomTM is the preferred piping network analysis and system modeling software, providing the engineer a logical and flexible graphical interface.

Equipment characteristics, analysis and output are tightly integrated with your system’s schematic representation. AFT Fathom implements a wide array of features without sacrificing the engineer’s need for a short learning curve and ease of use.

Comprehensive Capabiliites

Just as the demands on your system design increase in scope, AFT Fathom 7.0 provides an amazingly broad scope of capabilities. Addressing open and closed loop systems, AFT Fathom includes a built-in library of fluids and fittings, variable model configurations, pump and control valve modeling and much more. AFT Fathom goes beyond the boundaries of fluid flow analysis, with pump energy cost analysis, thermal analysis capabilities including piping heat transfer, heat exchanger modeling and varying fluid properties.

New in Version 7.0

• Enhanced ExcelTM file import including selected pipe input parameters
• Pump vs system curve shows operation with multiple combinations of pumps running
• Input graph display for pipe intermediate elevations and valve open parent Acv and flow area Vv
• Simultaneous display of output parameters with differing units (e.g. flow displayed in qpm and m3/hr at the same time)
• Pipe volume available as new output parameter

Today’s complex compressible flow systems surpass the best traditional design methods resulting in missed opportunities to reduce cost. Sizing for minimal system cost requires determining the best combination of a staggering numbering of variables is now beyond the best of human intelligence can handle. Now, AFT TitanTM, with IntelliFlowTM, eliminates these boundaries. Providing the systems engineer a new technology to intelligently size the system as a whole, your compressible flow piping system can be optimally sized resulting in substantial cost savings. With comprehensive system modeling capabilities, a flexible graphical interface and an advanced optimisation engine, AFT Titan offers a quantum leap improvement to the traditional pipe and duct design process.

Cost Reduction Through Intelligent System Sizing

Traditional engineering methods are limited in their ability to select pipes, ducts and equipment sizes on a system basis. Even simple systems will have billions of potential size combinations to consider for their various components, far too many to evaluate by traditional methods. In contrast, intelligent system sizing selects all components simultaneously as a unit. This is the essence of IntelliFlowTM technology. AFT Titan harnesses this technology to automatically identify and select the lowest cost design to meet your requirements.

IntelliFlow combines powerful network pipe flow analysis algorithms with state-of-the-art numerical optimisation algorithms to intelligently evaluate the complex interaction of system design variables. The system design is repeatedly perturbed and reanalysed to define the shape of the design space, revealing combinations of design parameters that minimize cost. Design constraints specified by the engineer direct the search in areas that satisfy design requirements such as pressure, velocity and compressor pressure rise. Searching continues until an optimum design is found, which is then presented to the user.
