FLUIDON releases new version 3.10 of DSHplus

FLUIDON, a provider of simulation and analysis of fluid power and mechatronic systems, has announced the release of the new version 3.10 of its simulation environment DSHplus. Starting today, DSHplus users with a valid maintenance contract will automatically receive new license keys. The new version will also be available for download on the FLUIDON web page.

New fluid property handling in DSHplus 3.10

With the new version FLUIDON introduces a new fluid property handling that allows users – in contrast to past versions – to include their own fluid property descriptions. In addition, the Bunsen coefficient (a measure of the gas dissolving capacity of a liquid) and the vapour pressure curve have been added as new material properties. With knowledge of the vapour pressure and the Bunsen coefficient, the pressure-dependent growth and transport of vapour and/or gas bubbles in liquid-filled pipe systems can be considered.

Improved simulation of gas and steam cavitation in pressure oscillation investigations

In particular, the simulation of pressure oscillation and water hammer problems benefits from the improved modelling, as – depending on the pressure level – the occurrence of gas and/or steam cavitation is to be expected. The correspondingly extended DSHplus pipe models have been validated based on published reference experiments. Also, the tried and tested models of DSHplus can now take the mechanical effects of water hammer or pressure pulsations on piping components into account by enabling the consideration of fluid-structure interaction (FSI library) during a 1D hydraulic simulation.

FMI 2.0 standard to replace DSHplus-STC for simulation tool coupling

In addition, the new version introduces the Functional Mockup Interface (FMI) 2.0 standard, replacing the former DSHplus-STC (Simulation-Tool-Chain) for simulation tool coupling. The Functional Mockup Interface is a tool independent standard for coupled simulations and supports model exchange as well as co-simulation.

'We are pleased to provide our customers as of today with the new release 3.10 of DSHplus,' said Heiko Baum, managing director FLUIDON GmbH. 'Even if not obvious at first glance, the new version offers many new options and library enhancements. Users of DSHplus are able to instantly continue their productive work and will not face any adoption problems with the new release.'


Altair customers can download the new version using the download link on the DSHplus page of the Altair Partner Alliance web page:





About DSHplus

DSHplus is FLUIDON's in-house 1D simulation environment, specifically designed for the dynamic, non-linear calculation of complex fluid power and mechatronic systems. DSHplus is used for the analysis of the dynamics of hydraulic and pneumatic systems, for system revisions, for component selection and design, for troubleshooting and for training purposes. In addition to various component libraries, DSHplus offers extensive options for postprocessing and simulation automation. Furthermore, the "Functional Mock-up Interface" (FMI) is supported, which guarantees a comfortable connection to other CAE tools. A PLC connection for the virtual commissioning of machines and plants rounds off the software's range of applications. Further information is available at
