StressCheck Demo: Comparing Manual Mesh and Automesh Results for a 3D Stepped Specimen
Abstract: the exact solution of a mathematical model should be independent of how the finite element mesh was generated (i.e. manually or automatically), the number of elements used to construct the mesh, and/or the polynomial orders of the element displacement functions. In this demonstration, we show how a 3D stepped specimen peak stress result converges to practically the same magnitude and location for two different meshing strategies.

When performing parametric structural analysis, ESRD’s p-element StressCheck® FEA software is always my preferred choice due to the excellent solution quality, parametric framework, and superior computational efficiency. In fact, I recently used StressCheck® to generate stress intensity factors along a parametrically defined elliptical crack-tip across 3,000 unique geometric configurations. Considering multi-body contact was present and all simulations were performed using a laptop, this was a task well suited for StressCheck®.
