Build 2023.12.0.7513

Release status - January 2, 2024

To access the latest DesignCalcs installation file, contact your account manager or support.

During installation, if an issue occurs with the Sentinel Run-Time Environment Installer, cancel the install and go to Installing or Updating the Windows Driver for the Hasp License for steps on how to complete a sentinel hasp installation. Once this is completed, install DesignCalcs again.

For a quick demo of the updates listed below, watch the following video:

New Features

• DesignCalcs now has multi-factor authentication and geofencing options to further protect user data and software usage.

• You 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 (e.g. UCS-23, UHA-23, UNF-23.1, and so on) in Section VIII-1 2023 have been updated as well as the Minimum Design Metal Temperature (MDMT) curve assignment per UCS-66 in Section VIII-1 2023. DC-10314, DC-10348, DC-10484, DC-10611

• The following updates have been made to reflect the 2023 ASME code edition updates:

  • The three tubesheet types within the software 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). DC-10698, DC-10769, DC-10780, DC-10791

• 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. DC-10671

• 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. The software now displays the 2023 edition options for older years, but the report now updates based on the year of selection (e.g. 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). DC-10622

• 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. DC-10566

• The following updates have been made to the JSON export:

  • General improvements have been made to the JSON export including warnings about unsupported components in the export and when licenses are not available. DC-10371

  • The JSON export now supports internal and external corrosion allowances at the component level and the vessel level. DC-10703

  • The JSON export now supports Cones. DC-10528

  • The JSON export now supports Nozzles in Cones. DC-10428

  • The JSON export now supports Skirts and Base Rings. DC-10440

Issues Resolved

• The thick walled expansion joint calculations for the outer and inner straights now work as expected. Previously, some of the UG-27 values were showing as failing when they should not have been. DC-10671

• The JSON export has been updated to no longer assume that the elliptical heads are 2:1. DC-10462

• The Lug and Support ring reports for ASCE 7-22 have been updated to correctly display when one of the new two-lettered site classes is specified. Previously, the site class incorrectly displayed twice without the site class selection being shown at all. DC-10600

• The lifting lug form for lifting lugs in cylinders is now enabled for all applicable cases. Previously, the Calculate Localized Stresses box was disabled for all cases. DC-10656

Miscellaneous

• The default Hydrotest selection for support calculations is now Max(Ptcalc, Pd) for all new vessel files. DC-10359

• The default B16.5 and B16.47 selection is 2020 for 2023 code vessels by reference via Table U-3/Table 1.1. DC-10337

• The About window now shows support for the 2023 Edition of the code. DC-10932

• The default code year is now 2023 for new vessels. DC-10932

• The software now opens the Material Selection faster. A message may display that the material is loading. DC-10805

• The message in the Lug form, suggesting the user check the repad for stresses per WRC-107 now suggest the user check the repad stresses with NozzlePRO. DC-10406

• The software now has some business logic coming from the CEI Interop DLL, shared by multiple programs. This requires a new license. DC-10550, CRTN-4584
