Automated Network Sizing (ANS)

An AFT Fathom Add-on Module

The ANS module uses IntelliFlow®, which uses a combination of advanced
numerical searching algorithms and pipe flow simulation. 
The technology
was developed by AFT and has been a 
solution proven to save capital
costs
. It evaluates the complex interaction of variables in your
system 
design, revealing combinations of parameters
that 
minimize cost.

Why Use the ANS Module?

Gone are the days of sizing each line individually. Automatically size all piping and system components in an integrated manner to minimize weight and cost. This is done using advanced numerical searching algorithms available in the ANS module.

The benefit to engineering design firms is that they can significantly reduce the costs on piping. Experience shows this reduction is typically 10-15%. 

Further, if design firms so choose, they can also directly minimize monetary cost of the entire piping system based on initial cost or even recurring costs!

Empower Engineers to Design for Tomorrow with Advanced Sizing Technology

One of the powerful benefits of system modeling is the ability to evaluate the effects of changing system parameters.
  • Size pipes to minimize pipe weight, duct volume, or system monetary cost
  • Input design requirements such as pressure, flow, velocity or NPSH to guide the automated sizing process
  • Reduce pump energy usage
  • Assign sized pipes and pumps to groups to enforce commonality of automated size selections
  • Automatically size pipes, pumps and valves to satisfy requirements across multiple design cases organized into different scenarios
  • Employ industry-leading searching algorithms to find the best sizing result
  • Easily import piping and equipment costs from Excel 

Save 10-15% on piping costs and energy costs!

Benefits:

  • Capital cost savings
  • Minimize the initial and life cycle cost of your system designs
  • Achieve inherent system flow balance
  • Ensure performance requirements are met over multiple design cases
  • Understand what really drives your design
  • Users familiar with AFT Fathom will be able to utilize the ANS module with little additional effort
The extra effort to perform automated sizing on an AFT Fathom model is as little as 1%

How it Works

With any AFT Fathom model, you can follow the path of the Sizing Navigation Panel (shown above) to enter your objective and requirements. Run the scenario and the ANS module will automatically size your pipes.

Simply follow the Sizing Navigation Panel to:
  • Sizing Objective: Select whether to minimize weight, volume or cost (this will determine your navigation path)
  • Size Assignments: Identify individual pipes, or common groups of pipes to be sized
  • Candidate Sets: Choose the range of allowable pipe sizes
  • Design Requirements: Input and apply design requirements to the appropriate pipes and junctions
  • Assign Cost Databases: (optional) For cost-based sizing, select the cost data for the piping and equipment
  • Sizing Method: Select an algorithm to use, or just follow the default choices
  • Dependent Design Cases: Select multiple operating cases you would like to include in the sizing
The ANS module intelligently adjusted the pipe sizes in this model of a cooling tower, reducing total pipe weight by 17%. Minimum flows through the Lube Oil Cooler and Steam Generator Condenser are maintained.
