FEPipe Essentials Training Course

Dynaflow Research Group has released a new online course: FEPipe Essentials. The objective of this course is to give FEPipe users a strong understanding of performing ASME VIII-2 “Design by Analysis” calculations using FEPipe and the many capabilities of the software. The course consists of 7 online modules based on video lectures, software tutorials and […]

Coupled Thermodynamic BOSfluids-Jive Simulations

BOSfluids Thermodynamic Module BOSfluids is known for its steady state, quasi steady state and transient flow solvers and the more recent interface to the structural solver of ANSYS. Recently the steady state solver of BOSfluids has been extended with a thermodynamic module. That is, given thermal boundary conditions, BOSfluids calculates the temperature profile within the […]

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 […]

Release ISOtracer 2.2

The next release of ISOtracer, version 2.2, is available. With ISOtracer you can model and mark up isometric drawings in a single operation. Simply trace along the piping on the drawings to create a 3-D model and position markers at the same time. This new version of ISOtracer includes the following improvements: New support for […]

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 […]

BOSpulse: New support for stepless flow control

An increasing number of reciprocating compressors are equipped with actuators that can regulate the opening state of suction valves to reduce the capacity (or flow) rate continuously from 100% to zero. This so-called stepless capacity or flow control has proven to be an effective way to save energy when operating a compressor at a lower […]

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 […]

BOSpulse: Improved structural analysis interface

The previous BOSpulse release brought a bridge between the flow domain and the structural domain in the form of a structural solver interface. This enables you to perform a forced mechanical response analysis without having to perform error-prone and manual conversions from the flow model to the structural model.   The structural solver interface has […]

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 […]
