CAEfatigue - Fatigue evaluation in the frequency domain or time domain.
CAEfatigue (CF) is used to conduct random response and fatigue evaluations of dynamic mechanical systems in the frequency domain or time domain.
The software is available for single input PSD loading with or without deterministic loads like sine-on-random, sine sweeps, sine harmonics, etc. The software also allows complex multi-event, multi-channel PSD loading with cross PSDs and the standard time domain analysis solutions like linear static superposition, the modal participation factor approach or the direct stress recovery approach. The software can handle virtually any size model with extreme speed and accuracy.
Why choose CF over other frequency domain competitor tools?
CF processes models from multiple sources including Nastran, NX Nastran, Abaqus, Ansys and Optistruct.
CF processes very large models (Tb+) with little difficulty.
CF allows the use of unlimited multiple correlated inputs and includes accurate calculation of the cross-correlation influences between inputs.
CF allows the inputs to be mixed loading (e.g. sine sweep, sine-on-random PSD, consecutive sines, etc. plus a mean (static) loading).
If you still want to work in the time domain, why choose CF over the competitor tools?
CF provide a TIME2PSD toolset to condition and convert time signals into PSD matrix files. Just push a button and your files are converted to accurately produce both direct PSDs and cross PSDs to take into account channel phasing.
CF is much faster because our software is newly developed using the latest programming techniques and processing algorithms.
CF for time domain is not a “bolt on” application to our frequency domain tool, it is created from the ground up to ensure the most seamless analysis possible.
CF gives you total control over the use of RAM and the number of processor by default.
CF provides a separate Load Scheduler toolset to let you create your own unique time domain loading from a single channel to a complicated, multi-channel, multi event loading. We do not charge extra for this.
CAEfatigue is available as a standalone product from MSC Software or use it through the MSCOne token system. CF is also the chosen technology that is embedded in MSC Nastran (NEVF).
