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.

“Aerospace materials scientists and structural engineers now have a new state-of-the-art software product called StressCheck®, which provides efficient and reliable analysis tools for composite bonded aircraft structures. A composites research team from the aeronautics industry, known as the Composites Affordability Initiative (CAI), has just completed an extensive study of current capabilities in the area of failure analysis tools for composite bonded joints. This study led the CAI team to unanimously choose StressCheck® as the software tool to replace as well as radically improve existing industry standard software currently used to size bonded joints.”
