BOSpulse, More Than a PULS Replacement
If you are looking for a replacement for Bentley PULS, then you have to look no further as BOSpulse is more than that.
Not only does it match the feature set provided by PULS, but BOSpulse also provides a growing set of features that are not available in PULS and that help you perform pulsation analyses faster and more accurately.
Easily Migrate from PULS to BOSpulse
Steady State Analyses
BOSpulse comes with an integrated steady solver that accurately calculates the average flow rates, pressures, and densities from the specified flow boundary conditions and reciprocating equipment parameters. This means that you do not have to specify the flow rates manually and that you can verify whether you have set up your model correctly by comparing the steady-state solution with the expected flow conditions.
Accurate Flow Solvers
BOSpulse enables you to choose between time-domain and frequency-domain flow solvers. The former involves the solution of the time-dependent, non-linear pipe flow equations by means of the method of characteristics. The latter is similar to the one offered by Bentley PULS, except that the one in BOSpulse is much more accurate for piping systems with small flow rates. This gain in accuracy has been achieved by incorporating a non-linear solution procedure for approximating the non-linear friction losses.
Model Variations
A pulsation analysis typically involves multiple operating cases, including a varying operating speed of the reciprocating equipment. BOSpulse enables you to handle these cases efficiently by means of scenarios and parameter studies. The latter involves defining a so-called parameter schedule that describes how the symbolic parameters are to be varied when performing an analysis.
Multiple Fluids
With BOSpulse you can specify multiple fluids within a single model. This greatly simplifies the analysis of systems involving chemical, mixing or separation processes. Fluid definitions can be saved to a database so that they can be re-used in multiple models.
Acoustic Modal Analyses
Besides API pulsation analyses, BOSpulse supports acoustic modal analyses with which you can determine the natural acoustic modes in a piping system. This enables you to gain a better understanding of the acoustic response of a system and to design effective mitigating measures for problematic pressure pulsations.
Custom Allowable Limits
BOSpulse naturally supports the latest editions of the API 674 and 618 standards. What is more, you can define your own allowable limits in the form of user-defined functions and apply those limits to an entire model or specific parts of it.
Import and Export Interfaces
By using the import and export interfaces provided by BOSpulse you can avoid manual, time-consuming and error-prone data conversions. BOSpulse can import piping models from pipe stress programs through its CAESAR II interface, and from CAD programs through its excellent PCF interface. You can export data, including shaking forces, to various types of files, including spread sheets and pipe stress data files.
Combined Acoustic and Structural Analyses
Using the structural solver interface, you can perform combined acoustic/flow and structural analyses (Design Approach 3) directly from within BOSpulse, provided that you have an ANSYS license. If this is not the case, then you will find that BOSpulse interoperates efficiently with various pipe stress applications.
Continued Development and Support
A purchase of a BOSpulse license is an investment in the future as BOSpulse is continuously being improved and extended with new features. By providing feedback and submitting feature requests you can directly influence the direction in which BOSpulse is developed, and make sure that you get more value out of your investment. In the event you have a question you can expect a prompt response from one of our software developers or engineers. They can also help you integrating BOSpulse in your work flow as you phase out Bentley PULS.
