Incompressible Pipe Flow Network Analysis & System Modeling
The most comprehensive system modeling software available with powerful incompressible pipe network flow analysis, heat transfer and built-in tools for modeling a wide range of piping system components.

Building on the most comprehensive piping system modeling software for  incompressible flow systems, the Fathom™ modules extend modeling capabilities into three areas-

• XTS - eXtended Time Simulation to model dynamic system behavior.

• GSC - Goal Seek and Control to automate the determination of input parameters that will yield desired output values and simulate control functions within systems.

• SSL- Settling Slurry models the effects of pumping fluids containing settling solids.

• ANS- Automated Network Sizing to size piping automatically against system design requirements within the initial capital investment, operation and maintenance, and life cycle design costs.  

Waterhammer/Surge Transient Pipe Flow Network Analysis
Waterhammer/Surge transients for liquid pipe networks. Transient modeling capabilities include pump speed variation, valve open/closure, relief valves, liquid level change, accumulator and surge tanks and more.

Building on the foremost software for calculating pressure transients in piping systems, the Impulse SSL Module models waterhammer effects on systems containing settling slurries.

• SSL - Settling Slurry models waterhammer effects on systems containing settling slurries.

• PFA - Pulsation Frequency Analysis helps identify and avoid resonant frequencies in systems, especially in those caused by positive displacement pumps.

Compressible Pipe Flow Network Analysis
Powerful compressible flow pipe network flow analysis and system modeling including adiabatic, isothermal and generalized heat transfer, modeling velocities up to and including sonic choking.

Building on the most comprehensive piping system modeling software for compressible flow systems, the AFT Arrow™ modules extend modeling capabilities two ways -

• GSC- Goal Seek and Control to automate the determination of input parameters that will yield desired output values and simulate control functions within systems

• ANS- Automated Network Sizing to size piping automatically against system design requirements within the initial capital investment, operation and maintenance, and life cycle design costs.

Steam & Gas Transient Analysis
xStream is a powerful fluid dynamic simulation tool for high-speed, acoustic transients that occur in steam and gas piping systems. Now you can accurately simulate how your steam and gas systems will respond to potentially disruptive transient events. .

Helps identify pipe acoustical frequencies to avoid resonance from excitation, especially in systems with reciprocating compressors.

• PFA - Pulsation Frequency Analysis helps identify and avoid resonant frequencies in systems, especially in those caused by reciprocating compressors.

Chempak provides a property database of up to 700 fluids and mixing capability to AFT Fathom, Arrow, AFT Impulse, AFT Titan and AFT Mercury. AFT Chempak Viewer allows the Chempak database to be used as a stand alone application while AFT Chempak Add-in makes the database information accessible within Microsoft Excel spreadsheets.
