Summary: This paper introduces a new approach to automatic mesh generation over composite geometry. This approach is based on an adaptation of advancing front mesh generation techniques over curved surfaces, and its main features are:
\(\bullet\) elements are generated directiy over multiple parametric surfaces: advancing front propagation is adapted through the extension to composite geometry of propagation direction, propagation length, and target point concepts,
\(\bullet\) each mesh entity is associated with sets of images in each reference entity of the composite geometry,
\(\bullet\) the intersection tests between segments are performed in the parametric domain of their images.
For the entire collection see [Zbl 1122.65002].
