DesignCalcs: 2023.12.0.7513 Release

The following features are available with the 2023.12.0.7513 Release of DesignCalcs:

• DesignCalcs now includes several updates from the 2023 edition of the ASME code:

  • Users can now add, delete, or edit the material properties from SC II, D 2023 for the allowable stress, yield, ultimate stress, modulus of elasticity, mean coefficient of thermal expansion, Poisson’s ratio, and density fields. Additionally, changes to the material tables (UCS-23, UHA-23, UNF-23.1, and so on) in the 2023 ASME code update of Section VIII, Division 1 have been updated as well as the Minimum Design Metal Temperature (MDMT) curve assignment per UCS-66.

  • The tubesheet types have been updated to support the 2023 code edition changes, including:

    • UHX references have been updated to 4.18.

    • The new coefficients CC, Cmdelta, Cmtheta, Cqdelta, Cqtheta, and Zeta C have been added.

    • The shell shape coefficients Lambda S and delta S have been updated to be based on mean diameter instead of inside diameter.

    • The channel shape coefficients Lambda C and delta C have been updated to be based on mean diameter instead of inside diameter and also to incorporate the new coefficients listed above.

    • The channel coefficient Omega C has been updated to incorporate the new coefficients listed above.

    • The channel membrane and channel bending stresses have been updated based on the new formulations.

    • The calculation for mu* has been moved from step 3 to step 1; for Utube Tubesheets, the calculation for MTS has been moved from step 2 to step 6; for Fixed and Floating Tubesheets, the shown tubesheet bending stress (tau) equation, when Ap and Cp are provided, has been updated to the new simplified form (this has no effect on the result).

  • The Flexible Shell Element (Thick Walled Expansion Joint) calculations have been updated to reflect changes clarified in the 2023 edition code. The updated code states the straight flange length is half of the length between the outer knuckle tangents for the outer straight and half of the the length between the inner knuckle tangents (if they exist) for the inner straight. This decreases the likelihood that UG-27 calculations will be required. Since this was a clarification, all code years for Thick Walled Expansion Joints will be affected.
  • Tube-to-Tubesheet weld references have been updated to reflect changes in the 2023 edition code. The former UW-20 strength based calculations have now been moved to UW-20.3; the former non-mandatory Appendix A calculations have been moved to mandatory UW-20.4; former Figure A details have been updated to Figure UW-20.2. DesignCalcs now displays the ASME 2023 code edition options for older years, but the report now updates based on the year of selection (a 2019 vessel will show Appendix A in the report while a 2023 vessel will show UW-20.4, but both will show UW-20.4 in the software).
  • The Unthreaded Area is now displayed on the Custom (Appendix 2) flange form for the bolting information to better support a clarification made in the 2023 edition of Section VIII, Division 1 in Mandatory Appendix 2. Old designs will set the Unthreaded Area value to the Root Area value. The bolt browser now supports this as well and all of the Unthreaded Area values are set to the Root Area values. In the calculation, the smaller of the Root Area or the Unthreaded area will be used. Since this is a clarification, it affects all previous code years.
• DesignCalcs now supports multi-factor authentication and geofencing options to further protect user data and software usage.

• CEI's new single-source-of-truth JSON file format allows DesignCalcs to have seamless integrations with other design and FEA software solutions like Finglow and Paulin Research Group (PRG). In this release, the following updates have been made:

  • General improvements have been made to the JSON export including warnings about unsupported components in the export and when licenses are not available.

  • The JSON export now supports internal and external corrosion allowances at the component level and the vessel level.

  • The JSON export now supports Cones.

  • The JSON export now supports Nozzles in Cones.

  • The JSON export now supports Skirts and Base Rings.
