CAEfatigue GUI (CFG)
Results generated by the CAEfatigue Software Suite can be visualized in commercial post-processing packages such as HyperView, however, we want to provide a simple, easy to use graphical user interface that can be operated without significant training, yet provides all the necessary visual information that is required by the user.

CAEfatigue Time2PSD
We want to provide a tool that engineers or designers can use too easily and accurately convert multiple time signals to PSDs included in the effects of cross channel phasing.

CAEfatigue VIBRATION - BASE SHAKE and CAEFatigue VIBRATION - MULTI
CF_BASE (single input) and CF_MULTI (multi input) enables users to perform a fatigue analysis in frequency domain with techniques that are often used for dynamic structural analyses

CAEfatigue VIBRATION (CFV) - BASE SHAKE
The CF_BASE tool provides rapid and accurate structural response and fatigue results for a single input stress loading with virtually no limit on model size being analyzed

CAEfatigue VIBRATION (CFV) - MULTI
The CF_MULTI provides rapid and accurate random response and fatigue solver results that have virtually no limit on model size being analyzed

CAEfatigue VIBRATION for Automotive Systems
CAEfatigue VIBRATION is a powerful domain random response post processor and fatigue solver that works with mixed random (Power Spectral Density) and deterministic loading sources in a way not currently possible with existing products.

White Paper: Frequency FE-Based Weld Fatigue Life Prediction of Dynamic Systems
In most aspects of mechanical design related to a motor vehicle there are two ways to treat dynamic fatigue problems, that is time domain vs. frequency domain approach. Time domain approaches are the most common and most widely used especially in the automotive industries and accordingly, it is the method of choice for the fatigue calculation of welded structures.

White Paper: Simultaneous Durability Assessment and Relative Random Analysis Under Base Shake Loading Conditions
For many automotive systems, it is required to calculate both the durability performance of the part and to rule out the possibility of the collision of individual components during severe base shake vibration conditions. The check for “collisions” has previously been done separately with the resultant “doubling up” of the analysis being both time-consuming and cumbersome. However, new technological advances now make it possible to do both these calculations at the same time and this paper will present results for an exhaust model analyzed using NASTRAN.

White Paper: Creating Accurate Surrogate and/or Accelerated Loads for Known Models or Structural Systems Types
For laboratory-based simulation, especially of parts or subsystems, there is a need (usually because of available test equipment) to simplify the loads down to single input loads one at a time (eg, X, then Y, then Z) and this poses significant challenges. Two common approaches are currently used. This paper presents the details of a new approach which is a variation of the FDS approach but using the actual system properties.

White Paper: OHB & CAEfatigue - Simultaneous Durability Assessment and Relative Random Analysis Under Base Shake Loading Conditions
For many aerospace systems it is required to calculate both the durability of the part and
to rule out the possibility of collision of individual components during severe base
shake vibration conditions.
Advanced frequency domain methods now exist to enable the durability assessment to
be undertaken fully in the frequency domain and utilizing the most advanced and
efficient analysis tools.

Fatigue, Composites & Optimization: Themes for Partner Presentations at the Americas Altair Technology Conference
Americas ATC 2015 had one of the highest attendance in history, with about 750+ users in a span of 3 days attending workshops and presentations. Close to half the number of partners from the APA were present to interact with customers and showcase their technologies. Sridhar highlights the key points covered in the presentations.
