BOSfluids has always provided support for both steady state and transient analyses. The latter typically involve simulations of flow conditions that change over a relatively short time frame. Simulations of slowly-evolving flow conditions over long time periods are often not feasible due to excessive computation times. The upcoming BOSfluids 6.1 release will therefore offer support for quasi steady state analyses that are aimed specifically at simulations of slowly-evolving flow conditions. This makes BOfluids an even more versatile tool for pipe flow analyses.
A quasi steady state analysis makes it possible to study the effects of changes in (large) piping systems such as (potable) water networks. Those changes may involve varying valve settings and pump operating conditions, changes in demand and supply, varying liquid levels in tanks, and more. Because fluid inertia effects are ignored in quasi steady state analyses, the flow conditions can be determined at (mostly) arbitrary points in time. This makes a quasi steady state analysis much more efficient than a transient analysis in these situations
The results associated with a quasi steady state analysis are handled in the same way as the results associated with a transient analysis. This means that all post processing capabilities provided by BOSfluids can be used in an intuitive way for quasi steady state analysis. Indeed, you can easily compare results for a quasi steady state analysis and a transient analysis for the same piping model so that you can validate whether a quasi steady state approach is justifiable.
This is only one of many other improvements in the upcoming BOSfluids 6.1 release. We are looking forward to inform you about all the other features in the very near future.
