What's New in SDC Verifier

Current Version

SDC Verifier 2026 R1

Old Versions

New Standards

DNV RP C 201 (2023)

Enables advanced buckling verification of plated and stiffened structures in accordance with offshore design practice, supporting certification-ready analysis for marine and wind energy projects.

ISO 19902 (1st, 2007) Connections

Enables design and verification of offshore tubular joints in accordance with international offshore standards.

API RP 2A-LRFD (1st, 1993) Connections

Allows engineers to perform compliant offshore tubular joint verification under US design requirements, expanding support for global energy projects.

Norsok N-004 (rev.3, 2013) Connections

Enables code-compliant design and verification of offshore tubular connections used in North Sea and global energy projects.

NACA standard

Enables buckling calculations for flat plates based on NACA airfoil formulations, extending SDC Verifier with assessment capabilities for airfoil-based structures, such as airframe skins, wing ribs and spars, flanges, fuselage frames, etc.

New features in SDC Verifier

Compatibility

Now compatible with Ansys 2026 R1, Simcenter 3D 2512, and Femap 2512.

Plate & Buckling Enhancements

Introduced the Edge Stress Method in plate buckling checks, enabling more accurate stability assessment based on actual FEM edge stress distributions.

Enhanced the Effective Plate Width tool to include girders, enabling comprehensive stiffener–girder interaction in stability checks.

Improved Panel Finder recognition: predefined girders are now automatically identified as girders (instead of stiffeners) with dedicated parameters, enabling stiffener/girder buckling checks according to DNV RP-C201 (2023).

Modeling

Mesh to Geometry Tool allows to create plate geometry from selected 1D/2D mesh elements.

Reporting

Added support for custom legends in reports, allowing two independent legend ranges within a single plot for greater visualization flexibility.

Improvements

Auto Update Model preference

If enabled – the model updates automatically when elements are added, edited, or removed, eliminating manual updates and streamlining the workflow.

Flow Table – Show Relevant Results Only

Allows tracking the same load set across all nodes, improving result visibility and making load effect analysis more transparent.

Result Manager Enhancement

Centralizes Checks, Tools, and Output Sets in a single interface, improving consistency and efficiency across all supported SDC platforms.

Remove Old Output Sets (Default Enabled)

Automatically clears outdated results during recalculation, preventing model overload and ensuring result consistency.

Bulb Profile – Dimensions Added

Displays dimensional information directly in the shape library, simplifying profile selection and reducing input errors.

Updated the default Solid Geometry Scale Factor to 1

Prevents unintended unit scaling during geometry export, ensuring consistent and predictable model transfer.

Added Warning when editing Model with Existing Results

Protects users from working with outdated results by clearly notifying when mesh changes invalidate previous calculations.

Plate Buckling checks – implemented Flat/Curved Validation

Improves transparency by clearly indicating when curved plates are not supported by the selected standard, preventing misinterpretation of results.

Bug fixes

Calculation Fixes & Standards correctness

Corrected the total utilization calculation to properly apply absolute values for axial forces and bending moments according to EN 1993-1-8 (2005), ensuring consistent results for symmetric connections regardless of load sign.
Fixed optimization failure when a standard used parameters from another standard.
Fixed incorrect calculation approach for Total Average Von Mises (Equivalent) stress.
Corrected default values in the ASME B31.8 (2018) standard settings, including the Load factor (k), which previously defaulted to 0 and could cause calculation errors.
Corrected formulas in ISO 19902 Standard (2007 and 2020): – Wave number (k) calculation formula.
– Final utilization factor (Um) formula for hydrostatic conditions.
The fatigue summation equivalent direction were not being passed from Load Group Parameter to Summation Parameter.
Governing load was incorrectly displayed in Extreme Table for Load Group.
Improved geometrical check behavior in Weld Standards where:
– Standard bounds were changed to Custom Formula on edit.
– Custom formula did not include the Overall limits parameter.
– Overall limits were not updated when switching standards.
Fixed missing results for Rainflow Fatigue Summation in the “Rainflow Summation Expand/Extreme Table” with Expand Table Type.

Stability & Crashes

Resolved crash scenario in ANSYS Mechanical 2025 R2 when selecting loads after relaunch.
Fixed crash when plotting in Stress Gradient tool for an unanalyzed project.
Fixed crash in SDC Verifier when closing project after removing Output Set links and editing Individual Loads.
Fixed update failure after deleting solid mesh included in Welds.
Fixed recognition freeze on models with circular bar connected to circular tube.
Fixed an issue where uninstalling SDC Verifier removed the version path stored in the sdc_ansys_link.json configuration file, preventing SDC for Ansys from launching

Results & Data Handling

Hot Spot Stress settings were lost after project recovery.
Generated check tables and plots were disappearing after editing Eurocode 3 Members parameters.
Connection Check results were not exported to Femap.
Fixed missing predefined Load Cases in copied Jobs.
Fixed empty parameter selection in Peak Finder Tool for Eurocode 3 Fatigue when “Fatigue Stress Overshoots” was selected.
Components Extreme Table selection was not shown after reopening the project.
Fixed failure to import project part views for ANSYS.

Recognition

Fixed incorrect plate recognition in Panel Finder when gaps were present.
Fixed recognition progress bar stuck in Connection Finder for specific models.

Performance

Fixed very low performance when using Load Group with many items.
