What Is Your Structural Model Not Telling You? Finding Hidden Modelling Errors and Inaccuracies in Your Analysis Results

Publication: Structures Congress 2018: Buildings and Disaster Management

ABSTRACT

Finite element analysis involves inherent approximations and numerical errors. In addition to these, the increasing size of structural models and the use of automated workflows for creating them can lead to hidden user errors in the said models. For the engineer to have confidence in analysis results, it is necessary to be aware of how these errors manifest themselves in models, what impact they have on analysis results, and, most importantly, how they can be detected. We present novel numerical techniques that the analyst can use to ‘debug’ their models and verify the accuracy their analysis results. These techniques have been implemented in software and have been successfully used by practicing engineers working on live projects.
