BOSfluids 7.0: Support for building 2-D piping models

switch-between-2d-3d klein

The ability to work with 3-D piping models has always been one of the fundamental features of BOSfluids. This not only sets BOSfluids apart from similar software, but also makes it possible to obtain more accurate results, especially if the flow conditions of interest are affected by the geometry of the piping system. On the […]

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 […]

BOSpulse: (Preview) New support for end caps

The upcoming version of BOSpulse will offer a new Cap node type with which you can more accurately model Pressure Suppression Devices (PSDs) and therefore perform more accurate API 618 and API 674 analyses. Modeling the acoustic length and volume of the piping system is of great importance for an API 618 or API 674 […]

Dynaflow Discussion – Safety Factors in Piping Industry

Piping models that you produce are not 100% accurate. To make sure that uncertainties in design do not immediately result in failures in your piping systems safety factors are used in the analysis. In the latest session of Dynaflow Discussion, Mick Bouman – project engineer, and Johan Bosselaar – senior engineer, discussed the safety factors […]

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 […]

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 […]

The J-integral Approach in Elastic-Plastic Fatigue Analysis

The J-integral Approach in Elastic-Plastic Fatigue Analysis by Tammo Dukker In a fatigue analysis one would like to investigate the susceptibility of a structural component to crack propagation under cyclic loading to determine the number of cycles until a failure occurs. Common techniques applied in a fatigue analysis follow from the results of a linear […]
