Extraction of minimum principal stresses for the aircraft keel beam analysis. Digital Engineering case study results (bottom right) compared well with StressCheck Professional's live dynamic extractions. In recent years, Digital Engineering contributor, NAFEMS instructor and FETraining.net developer Tony Abbey has put together a list of practical engineering simulation case studies, walk-thrus and software overviews for a variety of FEA software tools. Watch as ESRD reproduces a selected set of his 3D detailed stress analysis case studies, and see how we compare with Digital Engineering's published results!
Engineering students and professionals alike want to know: are singularities "real"? And if so, when they appear in our solutions, what are we supposed to do with them? Regarding the practical question of what to do with singularities; we need to distinguish between cases where singularities are just nuisances and where a singularity is the object of simulation.
In this S.A.F.E.R. Simulation post, we'll explore Five Key Quality Checks for verifying the accuracy of FEA solutions. To help us drive the conversation in a practical manner, we selected a widely available and well understood benchmark problem to model, solve and perform each Key Quality Check using ESRD's flagship FEA software, StressCheck Professional.
