I take it you are interested in the time-dependent case. These two are good places to start src/ts/examples/tutorials/ex22.c - 1D advection-reaction src/ts/examples/tutorials/ex25.c - 1D "Brusselator" reaction-diffusion This example has more quirks, the physics is more complicated, and not all the algorithmic combinations work. src/ts/examples/tutorials/ex10.c - 1D non-equilibrium radiation-diffusion with Saha ionization model For 2D and 3D, there are other examples, either with different physics or not time-dependent. But the code structure is the same regardless of the dimension, so I recommend looking at the simple examples above (ex22 and ex25). -------------- next part -------------- An HTML attachment was scrubbed...
