-
- Piping code EN 13480-3 (2017) is updated to EN 13480-3 (2017)/A2:2020. Refer to Piping Code Compliance section of CAEPIPE Code Compliance Manual for more details.
-
- For Piping code = ASME B31.1 (2020), Forces and Moments for Sustained and Occasional loads are now combined as per para 104.8.4 (b) of ASME B31.1 (2020) for computing Occasional Stresses. Refer to Piping Code Compliance section titled ASME B31.1 (2020) in CAEPIPE Code Compliance Manual for more details.
-
- Allowable nozzle loads calculation for nozzles to spherical and cylindrical shells as per European code EN 13445-3: 2009 is updated to EN 13445-3:2014/A8:2019. Refer to Section titled “Nozzle Evaluation” in CAEPIPE Technical Reference Manual and CAEPIPE Code Compliance Manual for details.
-
- Improved Modal analysis algorithm for Eigenvalue (frequency) extraction. With this improvement, CAEPIPE can now extract much higher modes (Eigen vectors).
-
- New feature is added to turn some wind loads ON and the remaining wind loads OFF for a portion of piping. This can be done by entering “Y(es)” or leaving it “Blank” respectively through Layout Window > Misc > Loads/Beam Loads > Wind Load 1/Wind Load 2/Wind Load 3/Wind Load 4.
-
- New feature is added for the user to specify either the “Ground Level” or the “Depth of soil above pipe centre line” while modeling soil in Buried piping so that CAEPIPE will automatically calculate the soil stiffnesses in three directions internally at all buried piping nodes.
-
- New feature is added to define “Connected Node” for Snubber.
-
- Flange Equivalent Pressure routine is updated as per NC.3658.1 of ASME Section III Class 2 (2017). Refer to section titled “Flange” in CAEPIPE Technical Reference Manual for details.
-
- New feature is added to show and print Valve Accelerations for Response Spectrum analysis including Maximum values in global directions. Valve Accelerations can be seen through Results Frame > Results > Accelerations > Mouse right click > Show Valve Accelerations. The same can be printed by selecting the option “Accelerations” from the print dialog.
-
- New feature is added to show Pipe NS/Pipe OD in Flange List and Flange Report. This will be useful for editing flange data and post-processing of flange report.
-
- “Connected Node” data is now output in TXT and CSV files for Skewed Restraint.
-
- Setting the environmental variable “EXPORT_INCHES” to “YES” will now export and import moment units in “lb-in” via MBF in addition to exporting and importing length units in “inches” via MBF.
-
- Another New feature is added for translating and rotating the graphics model in Graphics Window using a mouse.
-
- In Translation mode, use: Ctrl + Mouse Left Button Down and Drag in Horizontal or Vertical for Horizontal or Vertical Translation of Model.
-
- In Rotation mode (Turn): Ctrl + Mouse Left Button Down and Drag in Horizonal or Vertical for Rotation in Horizontal or Vertical plane.
-
- Displacements results are hidden from “Support Load Summary” as adding “algebraically” displacements for Unsigned load cases such as Seismic load case with displacements from signed cases such as Operating load case is not suitable for models with non-linearities.
-
- MBF format is updated to be compatible with CAEPIPE Version 10.40. See Appendix A of CAEPIPE User’s Manual for details.
-
- CAEPIPE User’s Manual, Technical Reference Manual, Verification Manual and Code Compliance Manual have been enhanced and updated to be in line with software version 10.40. These Manuals can be downloaded from here.
-
- Bug Correction: In-plane and Out-of-plane Moments at Branch Nodes are NOT transformed properly while computing Creep Stresses for Piping Code = EN 13480. This bug exists from CAEPIPE Versions 9.00 through 10.30.
-
- Bug Correction: Access violation while exporting the Jacketted Piping stress layout with Guides located on Jacketted Piping to 3D Plant Design system through Layout Window > File > Export to 3D Plant Design.
-
- Bug Correction: Type column is output as “Anchor” instead of “Nozzle” in Specified Displacements output for Nozzle in TEXT file format through File > Print > Print to file > Text File (*.txt).
-
- Bug Correction: Structure Occupancy Category selected other than III in Wind-ASCE/SEI 7-16 dialog NOT saved in model file for ASCE/SEI 7-16 Wind parameters defined through Layout window > Misc > Wind – ASCE/SEI 7-16.
-
- Bug Correction: For Piping Code = IGEM (2012), Local forces and moments screen was displaying the Ip, It and Is corresponding to Cyclic SCF for Sustained and Expansion load cases. This bug exists from CAEPIPE Version 10.10 through 10.30 but did not affect the stress calculations.
