BOSfluids Tutorials

Below you will find a number of tutorials that guide you through the software. If you are a novice user, the first one to read is the Getting Started tutorial.


The other tutorials demonstrate how to setup particular simulations in BOSfluids.

Getting Started

The “Getting Started” tutorial guides the user through the process of building a model, defining boundary conditions and the basics of post- processing. This tutorial is designed for people who are not familiar with the software and shall demonstrate the basic features.


Valve closure and transient pressure wave

The “Valve closure and transient pressure wave” is a 3 part tutorial describing pressure wave development within a piping system due to valve closure. Part 1 describes the pressure wave and reflection and transmission due to varying diameter piping system. Part 2 discusses the phenomena of a closed-closed system and reflection of pressure waves. Part 3 describes the procedure to correctly model valve closures in a piping system.

Water hammer

The “Water hammer” tutorial is a 3 part tutorial describing the phenomena of water hammer in a piping system and how BOSfluids can be used to examine the resulting pressure spike and unbalanced forces in the system. The first part describes the creation of the BOSfluids model and the set-up of the analysis.The second part continues with the post-processing of the simulation results. The third part describes how unbalanced forces can be exported by BOSfluids and imported in the pipe stress analysis program Caesar II to perform a dynamic stress analysis.

Safety relief valve

The “Safety Relief Valve” tutorial describes the modeling theory of safety relief valves within BOSfluids including an example demonstrating the use of a safety relief valve in a tank filling scenario.


Tube rupture

The “Tube Rupture Modeling” tutorial describes the theory and modeling process of a tube rupture event using the special element type “Rupture element” in BOSfluids. It covers the algorithm BOSfluids uses to model the rupture event and a worked out example of how to include a rupture element in a system.


BOSfluids demonstrations

On the DRG YouTube channel various demonstration movies of BOSfluids are available. Demo’s are given on the 3-D viewer, the output interfaces and the BOSfluids scenario feature.
