Recent improvements

  • The PulsimSuite acoustic time domain solver speed has increased up to a factor 3
  • Parallel computing now available for even more calculation speed
  • Include user-built ANSYS models (e.g. compressor manifold) into the PulsimSuite-generated models
  • Fully automated interfacing between acoustics and mechanics
  • Automatic report generation in Word or Excel
  • Compliance checking of pulsation-induced shaking forces
  • Straightforward handling of parallel systems

Other highlights of PulsimSuite

  • Full Graphical User Interface control of model building, definition of operating conditions, and results analysis
  • Modern, intuitive 3D Graphical User Interface (multiple-select, copy/paste, rotate/translate/mirror, etc.)
  • Acoustics (pulsations) and pulsation-induced mechanics (vibrations, cyclic stresses) are calculated by a button-click, from one single model
  • Validity checking as you work
  • User selectable unit systems (SI, European customary, English, US customary)
  • Results displayed as colors on the pipe system, with automatic code check for API 618/674
  • Easy identification and visualization of worst-case pulsation/vibration resonances with the innovative "hover-and-click" functionality
  • No model complexity limits
  • CAD import of pipe systems from PCF files
  • Time domain solver ensures accurate simulation of non-linear effects like (cylinder) valve opening/closing, and damping by friction
  • Realistic source model (cylinder with influence of pulsations reflected from piping)
  • Ability to simulate controlled cylinder valves capacity control
  • Databases of standard piping, beams, flanges, and valves
  • Reliable, validated models with a sound track record in the industry
  • High-quality support from the TNO PULSIM people, a group with over 45 years of consultancy experience in the field.


  • Any Windows 64-bit PC (Windows 7 or higher) will suffice
  • For up to a factor 3 computation speed increase, a modern processor is required (e.g. INTEL or AMD from year 2012 or more recent)
  • Any current graphics card will be sufficient for pleasurable 3D model handling
  • For larger pipe systems: 16GB of RAM, SSD hard drive.
  • MS Word report generation: MS Word version 2010 or higher, English version
  • MathWorks MCR version 9.2 (free download from MathWorks site)
  • In case of using the Mechanical Module (calculating mechanical vibrations and cyclic stresses): ANSYS Structural
