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.
