BOSpulse 5.0: Improved model building user interface

The upcoming BOSpulse release, version 5.0, comes with a new set up of the first two top-level tab pages in the user interface. This change improves the distinction between the actions that operate on the main model and those that operate on a sub-scenario. This change makes it possible to skip the Scenarios tab page […]

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 4.2 released

After the release of BOSfluids two weeks ago, DRG is pleased to announce the release of BOSpulse¬†version 4.2. BOSpulse is a comprehensive software solution for performing pulsation analyses of piping systems involving reciprocating equipment. Our software provides a complete solution for engineers looking for a tool to solve their acoustic and mechanical response problems for […]

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 […]
