A new "SN from m and c" material model support simple SN description, along with access to the full material database.

Benefits:

-    Ease of use: visualization of channel and overall envelopes

-    Simplification: damage equivalent load across multiple events

-    Insight: consistent comparison across multiple events

Who needs it:

-    Durability/fatigue CAE engineers performing frequency domain life estimations

-    Test engineers processing equivalent/simplified shaker loads

New Frequency domain envelopes in CAEfatigue

Description:

New envelope analysis capabilities have been implemented to enhance result visualization across all frequency-domain solvers. Enables the display and statistical analysis of envelopes when connected to FFT, PSDM, or Load Scheduler inputs. Generation of damage-adjusted envelopes, allowing for the normalization of signal envelopes based on calculated damage potential.

Benefits:

-    Ease of use: visualization of channel and overall envelopes

-    Simplification: damage equivalent load across multiple events

-    Insight: consistent comparison across multiple channels/events

Who needs it:

-    Durability/fatigue CAE engineers performing frequency domain life estimation

-    Test engineers processing equivalent/simplified shaker loads

Improved visualization and parameter filtering in Robust Design

Description:

This release significantly advances the Robust Design analysis capabilities with new visualization, parameter filtering and debugging tools. A new "Convergence Description" in the Ant-Hill view allows engineers to track Spearman and Pearson correlation quantities as sample sizes increase. The Decision Map now drives a specialized fringe Description for visualizing element-based correlations, and export-to-csv functionality has been integrated directly into the map to respect active filters.

Benefits:

-    Ease of use: correlation visualization as model fringe Descriptions

-    Efficiency: deeper insight into statistical convergence

-    Collaborative: easy filtering and exporting of metamodel parameters

Who needs it:

-    Structural CAE engineers performing stochastic function studies and uncertainty quantification

Random Response Fatigue Analysis in CAEfatigue

Description:

A new workflow has been implemented to support fatigue calculations directly from random response data (Nastran H5). This capability, driven by the new psdresp load type , allows frequency-domain fatigue analysis using response PSDs generated by external solvers like Actran or Nastran, without the need for transfer functions. The implementation includes a dedicated "Random Response" load scheduler event, control file generation, and support for both single and multi-event scenarios.

Benefits:

-    Ease of use: direct result access with dedicated Random-Response option

-    Speed and efficiency: no need to store/read transfer functions or calculate PSDs

-    Collaborative: allows for vibroacoustic DFS and fatigue combining Actran and Nastran

Who needs it:

-    Structural and vibroacoustic CAE engineers performing durability assessment under random vibration excitation typical of Aerospace and Defence.

Product improvements and enhancements

Relevant product improvement in CAEfatigue 2025.2

Weld Analysis Enhancements

-    Thickness correction support for frequency-domain workflows. H5 result format now support thickness correction, ensuring accurate stress scaling for shell elements in weld fatigue calculations.

-    Abaqus ODB reader features intelligent cache management and enhanced spot weld parsing for complex coupling definitions.

Worst Layer

-    The Fringe Descriptionter now includes a "Worst" layer option. This feature calculates the maximum (or minimum, for inverse metrics like FOS) value for each element across all layers. Specifically helpful for composite layered output (frequency domain only).

Table Import/Export Enhancements

-    Directly import data into tables from a variety of file formats, including Control Files (CF), CSV, and Time History files (RSP, DAC, TXT, PCH). Additionally, table data can be exported to CSV.

Aero Load Spectrum Scalability

-    The Aero Load Spectrum capability has been optimized to handle a significantly larger number of load cases.

-    A new, simplified data entry method has been introduced, streamlining the configuration process for complex aero-structural models while maintaining full backward compatibility.

Performance and output

-    This release includes many performance enhancements including faster DETLOAD, significantly faster

LMTRANS with H5.

-    The solver now produces a combined H3D file by default removing the additional step of running an external utility.

Documentation updates

-    A comprehensive review and update of the User Guide examples has been completed. Examples have been verified and aligned with the current software version, ensuring that users have access to accurate, up-to-date resources for learning and troubleshooting.

Defect fixes

-    A comprehensive list is available with the release notes.



CAEfatiqueis a random response and vibration fatigue solver for the frequency domain plus a fatigue solver for the time domain. It works with mixed random and deterministic loadings or standard time domain-based loadings to provide fatigue life and damage predictions, as well as several forms of response statistics. It is exceptionally fast, easy-to-use and capable of handling very large models. The software also offers tools for loads management including digital signal processing, as well as a Robust Design feature that allow users to analyze the robustness of their FEA models to variations in FEA solution parameters.  Along with these fatigue tools the CAEFatigue software includes state-of-the-art methods for loads conditioning (Fourier transforms), test design and correlation.
