SDC Verifier 2024 R1.1: New Possibilities with Enhanced Functionality and Robustness

This latest release, SDC Verifier 2024 R1.1, is a testament to our commitment to continuous improvement. It delivers significant enhancements that expand your capabilities, refine your analysis accuracy, and elevate your overall user experience. 

What’s New in SDC Verifier 2024 R1.1

Unlocked geometry commands for all license levels 

SDC Verifier 2024 R1.1 democratizes the design process by removing license-level restrictions on geometry commands. This means that whether you’re using a Beams, Beams and Plate, or All elements package, you now have the full power of SDC Verifier’s geometry tools at your fingertips. 

This newfound flexibility empowers you to: 

• Tackle more complex design challenges. With an expanded toolkit, you can model intricate structures and components that were previously difficult or impossible to achieve. 

• Iterate faster and explore more options. Quickly generate and modify geometric models to evaluate different design approaches and find optimal solutions. 

• Streamline your workflow. Eliminate the need for workarounds or switching between software tools to create the geometry you need. 

Limited elemental results calculations depending on license level 

In SDC Verifier 2024 R1.1, we’ve fine-tuned our approach to results calculation to align with the specific capabilities of each license tier. This ensures that users get the most relevant and accurate results for their particular design workflows while maintaining the software’s optimal performance.

What this means for you

• Beams Package: Access essential results like nodal displacements and reaction forces from modal analysis, enabling you to assess the dynamic behavior of your structures. While detailed stress calculations from modal analysis might be limited, you’ll still get valuable insights into your beam structures.
• Beams and Plate Package: Unlock a wider range of results, including stress calculations relevant to beam and plate structures, as well as displacements and reaction forces. Gain a deeper understanding of your designs’ performance under various loads.
• All elements Package: Enjoy unrestricted access to the full spectrum of results, including detailed stress, strain, displacement, reaction forces, and other data for the most comprehensive analysis of solid structures.

Why this approach

1. We recognize that different licenses cater to distinct design needs. By aligning results with your license type, we ensure you’re getting the most accurate and actionable information for your specific projects.
2. This approach prevents users from importing results from higher-tier licenses (e.g., Solid) and using them with lower-tier licenses (e.g., Beams) where those specific calculations are not permitted.
3. Limiting calculations based on license tier ensures that SDC Verifier remains efficient and responsive, even with large and complex models.

New “Stitch” command 

With SDC Verifier 2024 R1.1, we’re introducing the new Stitch command.

The Stitch command intelligently merges adjacent surfaces or solids into a single, unified entity.

It automatically detects and resolves gaps or overlaps between the selected objects.

The result is a clean, watertight model that’s ready for analysis.

Why it matters

1. The Stitch command eliminates the tedious manual work of merging objects and fixing inconsistencies.
2. By automating the process, the Stitch command reduces the risk of human error and ensures a more accurate representation of your design.
3. The command can be used on a variety of object types, including plates, shells, and solids, making it a valuable addition to your modeling toolkit.

Whether you’re working with imported CAD data or creating complex models from scratch, the Stitch command streamlines your workflow and helps you achieve high-quality results faster.

A More Stable and Reliable SDC Verifier 

We’re committed to providing you with a seamless and reliable user experience. In SDC Verifier 2024 R1.1, we’ve tackled several critical bugs that were impacting your workflow and software stability: 

Report Designer Crashes Eliminated 

We’ve resolved several crashes that occurred when editing reports or changing parameters within checks.

Export Functionality 

We’ve fixed issues where the software would become unresponsive when exporting recognition items to groups. This improvement streamlines your data management and reporting processes. 

Accurate Group ID Creation 

We’ve addressed a bug that caused incorrect group IDs to be generated when exporting components to groups. This ensures data integrity and consistency in your models. 

Simplified Installation Process 

You no longer need to worry about missing dependencies. We’ve integrated the Microsoft Visual C++ Redistributable into the installer, making the installation process smoother and more straightforward. 

Enhanced Accuracy and Reliability in SDC for FEA 

SDC Verifier 2024 R1.1 brings a host of improvements to SDC for FEA, ensuring greater accuracy and dependability in your analysis workflows: 

Formula Corrections 

We’ve meticulously reviewed and corrected formulas across a wide range of standards, including FKM, Eurocode3, API RP 2A-WSD, BV NR615, AS 4100, and AISC ASD. These corrections address issues like incorrect moment calculations, shear area reductions, and other calculation errors, ultimately leading to more precise and reliable results. 

Crash and Stability Fixes

We’ve resolved crashes that occurred when using SDC Verifier remotely or after periods of inactivity. Now you can confidently work on your analyses without interruption, even in remote environments. 

A crash that occurred when editing plates in Panel Finder has been fixed, ensuring smooth operation of this essential tool. 

User Interface and Reporting Improvements 

A misleading message that appeared in SDC for Ansys when working with suppressed bodies has been eliminated, providing clearer feedback during your analysis. 

We’ve corrected an issue in SDC for Femap where reference points were incorrectly set when creating cross-sections from the shape library. This ensures accurate geometry representation and analysis results. 

Overall Impact

These enhancements collectively result in a more robust and reliable SDC for FEA experience. You can trust that your calculations are accurate, your workflows are uninterrupted, and your analysis results are dependable.  

Upholding the Highest Standards of Accuracy 

For our most technically inclined users, let’s delve into some of the key formula corrections in SDC Verifier 2024 R1.1. These refinements may seem subtle, but they have a profound impact on the accuracy and reliability of your analysis results. 

FKM (6th, 2012): Fatigue Calculations 

In the FKM standard, we identified and corrected errors in the calculation of the Utilization factor for checks related to fatigue analysis (constant and variable amplitude stress spectra). These corrections ensure that fatigue assessments are more precise, giving you greater confidence in your design’s ability to withstand cyclic loading. 

Eurocode3 Welds 1D (EN1993-1-8, 2005): Stress Calculations 

Several parameters within the Eurocode3 Welds 1D checks were incorrectly calculated, leading to potential inaccuracies in stress assessments. We’ve meticulously rectified these formulas, ensuring that stresses such as Normal Stress, OP Shear Stress, and IP Shear Stress are now computed correctly across various checks (P1, P2, P3, P4). 

Eurocode3 Connections (EN 1993-1-8, 2005): Limit State Checks 

We’ve refined the limit state checks in Eurocode3 Connections to ensure that the limits specified in Table 7.8 are applied only to the appropriate connection types (RHS chord with RHS or CHS braces). This correction ensures that your connection designs adhere to the code’s requirements. 

Additional Corrections 

We’ve also made formula corrections in other standards, including: 

• API RP 2A-WSD (21st, 2007): Overall check 

• BV NR615 Plate Buckling (2023): Plate buckling check 

• AS 4100 (2020): Shear check 

• AISC ASD 89 (9th, 1989): Section I check 

These corrections address a range of issues, such as missing parentheses, incorrect divisor placement, and omitted terms. While seemingly minor, these errors could lead to significant deviations in calculation results, potentially impacting design safety and efficiency. 

By addressing these formulaic discrepancies, we’re not just fixing bugs — we’re upholding the highest standards of engineering accuracy. This meticulous attention to detail ensures that SDC Verifier remains a trusted tool for engineers and designers who demand precision and reliability in their analyses.
