SUMMARY:Integrated geometric modelling and computational analysis using di
 stance fields - Matija Kecman - PhD Student

DESCRIPTION:In industrial settings engineers often employ a highly decoupl
 ed design-through-analysis workflow. Geometry models are first created wit
 h Computer-Aided Design (CAD) software and then discretised with a boundar
 y-conforming mesh for finite element analysis (FEA). This cumbersome multi
 -step procedure is costly\, error-prone and obstructs an iterative design 
 process. This talk will introduce an immersed boundary finite element tech
 nique that is based on non-boundary fitting structured grids. Generalised 
 distance fields are used for both describing the geometry and enforcing th
 e boundary conditions\; complex mesh generation is thus avoided and seamle
 ss integration of CAD and FEA becomes possible. Additional advantages with
  respect to conventional methods include\, for instance\, robust handling 
 of poor quality CAD input\, filtering of overly resolved geometric details
  and a built-in ability to efficiently manipulate geometry using Boolean s
 et operations.
