Upcoming BOSfluids release offers a steady state license option

BOSfluids is mostly known and used for transient flow analyses. However, it also provides a robust, fast and accurate steady state flow solver that can handle systems filled with liquids or gases. The upcoming BOSfluids 7.0 will offer a steady state license option that makes BOSfluids a very capable and cost-effective solution for the analysis […]
BOSfluids: Two-phase flood and drain analyses

When an empty, or gas filled, piping system is rapidly filled with a liquid, then significant forces can be exerted by the liquid on the system, especially when the liquid hits a significant flow restriction or the end point of a pipeline section. Indeed, there have been multiple incidents involving firewater systems in which these […]
BOSpulse support added to CSiPlant

BOSpulse support has been added to CSiPlant. As of version 7, CSiPlant is able to import the harmonic, pressure- induced forces calculated by BOSpulse. This means that you can use CSiPlant, and its non-linear transient capabilities, to assess the structural response of piping systems that are subjected to pressure pulsations resulting from reciprocating pumps and […]
BOSfluids: Improved pump model and user interface

Pump failure is a common cause of problematic transient flow conditions in piping systems. Simulation of pump failure is therefore an effective way to assess the robustness of a piping system before actual damage can occur. The pump model implemented by BOSfluids uses built-in pump curves to simulate the operating conditions of a pump after […]
BOSpulse: New support for generating torque graphs

The reciprocating compressor models implemented by BOSpulse require a substantial number of input parameters that affect the magnitude and shape of the generated flow rate. As the flow rate is the main source of the pressure pulsations, a small mistake in the input parameters can lead to an inaccurate or even invalid API assessment. To […]
BOSfluids 6.2: Improved and more efficient user interface

The BOSfluids user interface has been improved in many visible and invisible ways in this new release. Although many changes are relatively small, together they make the user interface significantly more efficient when creating and modifying piping models. One change concerns the Piping tab page that requires less screen space so that more screen estate […]
BOSfluids 6.2 released

DRG is pleased to announce the next release of BOSfluids, version 6.2. BOSfluids is our powerful fluid dynamic simulation tool to perform surge analyses, simulate pump failures and analyze waterhammer events in an interactive and visual way. The video below shows the highlights of the 2021 version 6.2. New features include: New support for simulating […]
BOSfluids: New support for simulating control systems

Piping systems frequently involve automatic control systems that adjust flow elements in response to changes in the flow conditions or to external events, such as timer switches. Setting up such control systems is a non-trivial task as the optimal control parameters tend to depend strongly on the piping system properties. Simulation is a very helpful […]
Webinar series: Power Your Dynamic Analysis with BOSfluids and CAESAR II

Dynaflow Research Group and Hexagon PPM join forces for a series of webinar sessions. In three webinar live sessions we will elaborate how leveraging BOSfluids and CAESAR II together takes the pain and stress out of Dynamic Stress Analysis. This unique combination saves your engineers time and resources, while ensuring accuracy with ease. Session 1 […]
