CAE Geometry Workshop

Held 14-15 September 2017 in Cambridge, England

Cambridge-UK.jpgCAD has for decades been the focus of engineering geometry. Based on the research in the Cambridge University Computer Lab in the 70’s by Ian Braid and colleagues, both Parasolid and ACIS emerged as kernels in many of today’s CAD systems. These are all NURBS based, so-called, solid modellers. With constraint management, direct modelling and fast computing, artefact design has gone wonderfully organic. But to ensure such artefacts are fit for purpose, physical simulation is required to check their behaviour in the domains of strength, heat, fluid flow, electro-magnetics. Hence the wide development of discrete representations that enable computation of these simulations, based on the CAD geometry (FEA, CFD, CEM etc).

Generating these discrete meshes or grids from CAD geometry has been a frustrating business.
Consequently, it is now widely accepted that engineering simulation needs a variant of the CAD geometry, which is becoming known as
CAE geometry.

During 14-15 September 2017, ITI ran a workshop on CAE Geometry to bring together those working in this field: end users, academics and vendors.

To encourage a full exchange of ideas, the workshop was an informal event with no published proceedings, with attendees able to present last minute results. Each presenter decided whether to distribute any presentation material. The presentations which have been provided are available via the links below.

Our earlier Medial Object Workshop, held in Cambridge October 2014 is similarly accessible here:

Most papers are provided below via the links in the titles. Dr Hugh Hunt’s presentation was an informal, after dinner entertainment talk – his website offers links to many of his popular talks:
