Transforming models for better simulation


FEATools transforms your piping model (CAESAR II and PCL-Gold) by including upgraded branch connections (with the addition of rigid elements and restraints) to better simulate real-world displacement and forces. The FEA-based calculations provide the necessary k-factors, SSIs and SIFs that will be added to every branch connection

FEATools is part of the PVPT (Pressure Vessel Piping and Tank) Design Suite.


More than 30 years of experience with piping analyses has been incorporated in FEATools and we are continuously transferring our knowledge and that of our users into new versions of the software.

The goal of the B31J code changes is to improve the accuracy of the calculation of SIFs, SSIs and k-factors for specific types of piping components and geometries. For some types of intersections, the new k-factor can easily be 2 to 8 times the old k-factor. These updated calculations have been provided as written formulas and tables which can be cumbersome and time-consuming to use.

FEATools automates the process of applying B31J to your entire CAESAR II model without requiring the user to be an FEA expert. Geometries that lie outside of the B31J code limits can still be analyzed and more accurate results achieved by using FEATools.

Step 1: Run the piping model file (CAESAR II or PCL-Gold) thru FEATools to generate FEA-based SIFs, SSIs & k-factors.

Step 2: Re-run your piping model file (CAESAR II or PCL-Gold) analysis to get more accurate stresses, loads, displacements and life cycles.
