Automated Mixed Dimensional Modelling With The Medial Object

This paper describes an automatic method for generating analysis models to be meshed with finite elements of more than one dimension, known as mixed dimensional models. Mixed dimensional models offer much reduced analysis times, while not compromising simulation accuracy to the same extent as fully dimensionally reduced models composed of 2D elements stiffened using beam elements, which are currently utilised in the aerospace industry. The techniques described make possible the automatic generation of mixed dimensional models directly from CAD, allowing for rapid iteration during early design.
