Abstract: In this paper we present a new approach to generate a mixed mesh with elements aligned to boundary/interfaces wherever is required. A valid element is: (a) any convex co-spherical element that fulfills the requirements of the underlying numerical method and (b) any element that satisfies domain specific geometric features of the model. The algorithm is based on the normal offsetting approach to generate coarse elements aligned to the boundary/interfaces. Those elements are later refined to accomplish layer density requirements. The main steps of the algorithm are described in detail and examples are given to illustrate the already implemented parts. As far as possible, we contrast this algorithm with previous approaches.
