== 3D Time dependent problem == | |||
Here is an example of a 3D time-dependent Advection-Diffusion equation that uses <code> lsode </code> | |||
The equation being solved is | |||
<math> - \mathrm{div } \left(.01 \nabla u - u \nabla \varphi \right) = 0 \qquad \mbox{ in } \Omega=[0, 1]^3</math> | |||
<math> \varphi = x + y - z</math> | |||
<math> - (.01 \nabla u - u \nabla \varphi \right) \cdot \mathbf{n} = 0 \qquad \mbox{ on } \partial\Omega</math> | |||
