One of the more recent additions to CAEfatigue that is not mentioned above is Robust Design.
Robust Design:
This new technology allows the user to re-run multiple MSC Nastran jobs consecutively while changing the input parameters for each run, the outputs from these runs are used to create a correlation map of input parameters vs. outputs. This shows what effect each of the inputs has on the outputs.
This allows the user to make better design decisions based on a holistic view of how the model reacts under all inputs.
Other interesting additions that are also noteworthy:
Automatic Generation of Load Scenario using Time Histories:
Various loading scenarios can be created automatically for a time-domain analysis, instead of having to create the loading scenarios manually. This automation will prevent errors from occurring and will speed up the analysis setup.
Multiaxial Stress Assement for Time Histories:
If the user is unsure which analysis method to use in CAEfatigue because the loading is proportional or disproportional, the new multiaxial assessment capability will allow the user to check the level of multiaxiality in the stress output. Based on the level of multiaxiality the user can decide if standard analysis methods or a more accurate critical plane approach should be used.
Composite Material Outputs from Nastran are Supported:
CAEfatigue can now import the stresses from a Nastran composite material analysis (using PCOMP or PCOMPG entries). This expands the interoperability of CAEfatigue with MSC Nastran output results.
