.. _secspatial: Spatial Differential Equations ============================== While the previous chapter was dedicated on temporal ODEs, this section will focus on pure spatial differential equations, i.e. without temporal derivatives, but with spatial derivatives instead. This necessitates a discretization in space of a given particular geometry in either one, two or three spatial dimensions. .. toctree:: :maxdepth: 5 :hidden: spatial/poisson.rst spatial/math.rst spatial/mesh.rst spatial/stokes.rst spatial/helmholtz.rst
