.. _chap.adv: More advanced issues in scientific computing ============================================ This chapter is the natural continuation of :numref:`chap.start`, where we have introduced the basic mathematical ingredients needed in the treatment of variational problems, as well as the convenient $\texttt{FreeFem}$ environment for their implementation. The present section builds on the contents of :numref:`chap.start` and jumps to slightly more specific tools, that are transverse to many application fields while being perhaps a little less widely discussed in the literature. .. toctree:: :maxdepth: 2 :caption: Contents: Meshing images Curvature Nonlinear problems Variational inequalities Level Set method I Level Set method II Going 3d <3dext.rst>
