A new feature has been added to perform Wave Load Analysis. Up to four (4) wave loads can now be analyzed. These wave loads can be entered through Layout window > Loads > Wave 1, Wave 2, Wave 3 and Wave 4. Wave loads can be applied either to the entire piping system or to a specific portion of the piping. Refer to the Section titled "Wave Load" in CAEPIPE User's Manual, CAEPIPE Technical Reference Manual as well as in CAEPIPE Code Compliance Manual for further details.

Piping code ASME B31.3 (2022) is updated to ASME B31.3 (2024). Refer to Piping Code Compliance Section titled ASME B31.3 (2024) in CAEPIPE Code Compliance Manual for details.

New Material library corresponding to ASME B31.3 (2024) is added. Refer to Piping Code Compliance section of CAEPIPE Code Compliance Manual for details.

New feature is added for assessing the piping loads applied to nozzles on Fired Heaters in accordance with API 560 (4th Edition, 2007). For further details, refer to the Section titled "Fired Heaters" in CAEPIPE Technical Reference Manual and CAEPIPE Code Compliance Manual.

New feature is added for assessing the piping loads applied to nozzles on Air Cooled Heat Exchangers in accordance with API 661 (7th Edition, 2013). For further details, refer to the Section titled "Air Cooled Heat Exchangers" in CAEPIPE Technical Reference Manual and CAEPIPE Code Compliance Manual.

New feature is added to generate "Elastic Response Spectrum" and "Design Response Spectrum" for both horizontal and vertical directions, as outlined in "EN 1998-1:2004". Refer to the section titled "Response Spectrum - EN 1998-1:2004(E)" in CAEPIPE Technical Reference Manual and in CAEPIPE Code Compliance Manual.

LISEGA Hanger Catalog is updated in line with LISEGA Catalog 2020. Refer to the revised catalog from the link https://www.lisega.de/wp-content/storage/uploads/2016/06/US_Katalog_GESAMT_low.pdf

The algorithm for identifying the Run and Branch elements has been updated. The new approach now uses the direction vectors of the connecting pipes at a branch connection, rather than relying on the Outer Diameters of the Run and Branch, to identify the Run and Branch elements at a branch connection.

New feature is added to validate, issue error message and stop the analysis, when the requirements as per Table 1-1 of ASME B31J (2023) for computation of Flexibility and Stress Intensification Factors are NOT met.

New feature is added to validate, issue error message and stop the analysis, when the requirements as per Annexure H of EN 13480-3 (2017)/A2:2020 for SIF computation are not met.

For all piping codes, a New option is added in Soil input for Buried Piping Analysis to compute Lateral Stiffness and Vertical stiffness of Soil with/without PUR Cushion using the procedure given in EN 13941-1:2019+A1:2021.

When a Spring Hanger is input with "Connected to" node, CAEPIPE will output the Angulation of Hanger with respect to the vertical axis in the Hanger Report for Operating Load Case 1.

New feature is added to prevent "Access Violation" error when the result "Support Loads" is selected for a Buried Piping model that has no physical supports.

Friction at the Limit Stop is now calculated in the Limit Stop local y and z directions and stored internally. These local friction forces are then transformed into Global Coordinate System when LCS to GCS is turned ON under Limit Stop Loads.

Non-linear algorithm for Limit Stop with friction defined is improved such that the sum of forces in the vertical direction is equal to the weight of the piping system, while the sum of forces in each of the two horizontal directions is equal to ZERO or Externally applied force in that direction, confirming static equilibrium of the total system.

New feature is added to not to allow the user to input the Yield Displacement Factor greater than 0.20 in Analysis Options related to Buried Piping Analysis.

New feature is added to perform Batch run of MBF file and output the results in CSV format for CAEPIPE 3D+ as it was done for CAEPIPE earlier. See Appendix A in CAEPIPE User's Manual for details.

New feature is added to output axial stress (Sa), bending stress (Sb) and torsional stress (St) in CSV format when Piping Code for Analysis is ASME B31.12 Part IP for Sustained Load case.

Algorithm for Refining Layout (for Buried Piping / Dynamic Analysis) is improved. This improved algorithm will prevent addition of nodes when the remaining length of element is less than 1 Outer Diameter of the Pipe.

Resultant forces shown for Nozzle under Support Load Summary results are now computed by including Radial, Shear y and Shear z. Similarly, Resultant moments shown for Nozzle are computed by including Torsional, Circumferencial and Longitudinal moments.

In frequency analysis, a minor improvement in mode shape extraction algorithm has been implemented.

MBF format is updated to be compatible with CAEPIPE Version 14.00. See Appendix A of CAEPIPE User's Manual for details.

CAEPIPE User's Manual, Technical Reference Manual, Code Compliance Manual and Verification Manual have been enhanced and updated to be in line with software version 14.00. These Manuals can be downloaded from the link www.sstusa.com/caepipe-docs.

Bug Correction: Level Tags were not displayed correctly in the input dialog for support types such as Anchor, Constant Support, and Limit Stop. This occurred because the level tags were sorted in the display.

Bug Correction: Participation Factors under Frequency results were not displayed correctly when the model contained Spring Hangers or User Hangers with the vertical axis set to Global Z in Multi-level Response Spectrum Analysis.

Bug Correction: Printing Support Loads results for Multi-level Response Spectrum to a TXT file that has Limit Stop/Spring Hanger/User Hanger/Snubber/Guide/Generic Support issues "Access Violation" at random.

Bug correction: X, Y and Z factors were output in Dimension Units while printing Spectrum Levels in TXT and CSV format. For example, X Factor of 1.0 was output as 25.4 in CSV and TXT output instead of 1.0 when the model is in SI units.

Bug Correction: For CAEPIPE and CAEPIPE 3D+ Hardware Key version, setting the License Expiry date beyond December 31, 2037 was issuing Access Violation.

Bug correction: For ASME B31.x codes with B31J turned ON, Axial SIF and Torsion SIF input by the User in the Bend input dialog were overwritten internally by the Axial SIF and Torsion SIF computed as per B31J.

Bug correction: Changing a Piping Code that uses "Cold Modulus" to a Piping Code that uses "Hot Modulus" was not saving the Modulus option properly in the model file.
