D2.4 First Release of the mesh generation/adaptation capabilities

This document presents a description of the parallel mesh adaptation library for the rst actual software release. Regarding the octree mesh-generation capabilities, the reader can refers to Deliverable 2.2. As it is discussed in Section 1.3.2 of part B of the project proposal there are two parallel research lines aimed at developing scalable adaptive mesh renement (AMR) algorithms and implementations. The rst one is based on using octree-based mesh generation and adaptation for the whole simulation in combination with untted nite element methods (FEMs) and the use of algebraic constraints to deal with non-conformity of spaces. On the other hand the second strategy is based on the use of an initial octree mesh that, aftermaking it conformal through the addition of template-based tetrahedral renements, is adapted anisotropically during the calculation
