Water hammer simulation in hydraulic piping systems

22. June 2017

H. Baum, FLUIDON GmbH, together with G. Scheffel, Parker Hannifin Kaarst, will be speaking at the industrial colloquium of the IFAS on July 7, 2017 about water hammer simulation in hydraulic piping systems.

The returncycle to the tank is often designed on the basis of the passed on rule of thumb. This can lead to damage to the system due to cavitation, water hammer and diesel effects. 
The simulation helps to understand the dynamic conditions during the braking process in a system-specific manner and supports the conception of corrective measures in order to avoid water hammer pressure.

FLUIDON at EATC 2017

25. May 2017

FLUIDON participates in the European Altair Technology Conference in Frankenthal from 26. to 28.6.2017 both as exhibitor and presenter of the lecture "Validation of Operation of a hydraulic Bascule Bridge".

The 9th European ATC will cover the complete spectrum of Altair offerings for Simulation Driven Innovation, from the application of simulation and optimization technologies to partner solutions as well as high-performance and cloud computing. The three-day event will be packed with valuable information from technical experts and thought leaders in Simulation-driven Innovation and offer content for users and everybody interested in product development techniques of all kinds, alike.

FLUIDON presents beside its portfolio of engineering services the preview of its simulation software DSHplus with an alpha version. In this way, interested parties are given the opportunity to take an early look at the largest revision of DSHplus so far.

The most striking change to DSHplus 4 is the new user interface, that differentiates no longer between modelling, parameterization and simulation, which makes it even more intuitive to work with. The previous function menu and toolbar had to give way to a modern ribbon. Functions that previously required the opening of a dialog window were summarized by task and can be accessed with a single mouse click. The consistent 64-bit architecture and the revised data core lead to a considerably acceleration of the simulation with DSHplus 4.

Download now: DSHplus 4 Preview

16. May 2017

As announced, the first alpha version of DSHplus 4 is now available for download as a preview. We have not finished yet - but you will already get an insight into the biggest revision of our simulation software.

DSHplus 4 offers you among other things

  • A new user interface that allows you to work faster and easier
  • A clearer library presentation to help you understand the variety of components
  • New multi-axis results graphs to present values more clearly
  • 64-bit architecture and a revised data core for faster simulations


Help improve DSHplus by reporting on your experience with DSHplus 4 Preview. Either directly from the program via the "Feedback" function in the menu bar or by mail to our DSHplus 4 alpha developer team.

DSHplus 4 at the HMI

3. February 2017

Discover the new DSHplus 4 at the Hannover Fair from April 24th until 28th 2017 at Booth F08/1 in Hall 21. From now on, DSHplus 4 alpha can be loaded from our website.

At Hannover Fair FLUIDON starts the preview program of its simulation software DSHplus with a first alpha version. In this way, interested parties are given the opportunity to take an early look at the largest revision of DSHplus so far at Booth F08/1 in Hall 21.

DSHplus is a simulation tool that was developed specially for dynamic, non-linear calculation of complex fluid power and mechatronic systems. You can use DSHplus for analysis of the dynamic of hydraulic and pneumatic systems, for system revision, for component selection and dimensioning, for failure diagnosis as wells as for training purposes. In addition to various component libraries, DSHplus offers extensive possibilities for automated simulation and analysis of results. Furthermore, the functional mock-up interface (FMI) is supported, which guarantees the connection to application-independent external CAE tools. A PLC connection for the virtual commissioning of machines and systems round off the application spectrum of the software.

The most striking change to DSHplus 4 is the new user interface, that differentiates no longer between modelling, parameterization and simulation, which makes it even more intuitive to work with. The previous function menu and toolbar had to give way to a modern ribbon. Functions that previously required the opening of a dialog window were summarized by task and can be accessed with a single mouse click.

Just in sight: A new User Interface

23. December 2016

Within the first half-year of 2017 an thoroughly revised version of our simulation software DSHplus will be released. There is still a lot to be done by then, but we want to show you some of the new features right now – a peek through the keyhole of our development division, so to speak.

What directly stands out at programme start is the new user interface. The former main menu and the icon bar have been replaced by a far more contemporary ribbon based menu bar that allows faster working. Functions are grouped by task and can be selected with one mouse click. Many settings which previously required the opening of a dialog window are now made directly inside the menu bar.

In addition, the user interface can be extensively customised. Modeling and library windows, messages, and scopes – all available windows can be anchored at any point in the program window or positioned arbitrarily on the desktop.

DSHplus: More is yet to come

21. October 2016

With DSHplus, FLUIDON provides fluid power engineers with a powerful tool. It has matured over decades, models and solver routines have been steadily improved, expanded and adapted to new findings. The next step is larger.

Engineers and software developers at FLUIDON are working hard on the next evolution of DSHplus. A new user interface combined with proven solver routines make working with DSHplus more pleasant and faster, preserving the high quality of results you are familiar with. The new software architecture ensures better stability, expandability and flexibility. New assembly group features provide a simpler reusablity of complex structures beyond model boundaries than before.

The next version of DSHplus is expected for the first half of 2017.

FLUIDON presentation on the Pump Summit 2016

12. October 2016

On November 29th Dr. Heiko Baum, managing director of FLUIDON GmbH, speaks at the Pump Summit 2016, about the analysis of pressure oscillation problems in piping systems with speed variable pump drives.

In 2016 the city of Düsseldorf, Germany, is again set to host the second Pump Summit on the 29th and 30th of November, 2016. Alongside the exhibition there will be a conference that serves as an independent communication platform for experts within the field of pumps and pump systems. The Pump Summit will focus on several industries, including water and wastewater, chemical processing, power generation, oil and gas, industry and building services, mining, food and beverage, pulp and paper and the pharmaceutical industry.

FLUIDON is included in the conference program with a lecture:

"Analysis of pressure oscillation problems in piping systems with speed variable pump drives"

Main topics of the lecture are:

  • Basics of pulsation excitation with speed variable pumps
  • Types of line termination (pump, valve or large container volume) and their influence on the pressure oscillation
  • Procedure for a simulative pressure oscillation analysis in piping networks
  • Visualization of the pressure oscillations in the so-called "pressure vector plot"
  • Simulative conception of remedy measures
