StressCheck Tutorial: Feature-Based Mesh Refinement
Abstract: Feature-based mesh refinement using the MeshSim automesher’s Curve method. Increase mesh refinement on selected boundaries, such as surfaces or curves, without affecting the global automesh. Discussion of the influence of the MeshSim Ratio parameter on feature-based mesh refinement.
Helpful Hint: for a specific number of element edges around a selected hole boundary, you may set the D/H value in the Curve method to be tan(pi/2/(n-1))/2, where n is the number of desired element edges. Note that the MinLen value may need to be decreased to allow n element edges.

“As the United States Air Force continues to extend the service life of their aircraft the Aircraft Structural Integrity Program (ASIP) has had to refine the methods it uses to analyze and predict fatigue crack growth. Through the use StressCheck®, coupled with AFGROW, we in A-10 ASIP have been able to more accurately model, predict and analyze critical aircraft structure for the A-10 and other types of structure for non-A-10 system managers. This also allows us within the A-10 to more accurately assess risk for decision makers, streamline aircraft inductions into scheduled maintenance and reduce cost for total life cycle management.”
