The computation of Stress Intensification Factors (i-Factors) and Flexibility Factors (k-Factors) has been updated in line with the ASME B31J (2023) revisions for the relevant ASME B31.x piping codes.

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/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.

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

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.

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.

New feature is added to run checkSTRESS as an offline tool with E3D, PDMS and CADMATIC.

"Support Load Summary" results will show the displacements results for all types of supports.

Shape Factor input field in Wind dialog is applicable only for "Velocity vs Elevation". Hence, Shape Factor input field is disabled in the Wind dialog when the option "Pressure vs Elevation" is selected.

New feature is added to Enable or Disable Dynamic Zoom in Graphics Window while using mouse scroll button for Zoom. This option can be modified through CAEPIPE Main Frame > Preferences > Disable Dynamic Zoom.

Bug Correction: When the output units was selected as "SI" in Plant Design, Pressure values were output in kg/cm2 in checkSTRESS instead of bar.

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.

Many other pre-processor, analysis and post-processor related enhancements valid for checkSTRESS in line with CAEPIPE Version 14.00.
