src/ts/examples/tutorials/ex26.c solves the same problem as that (since removed) src/snes/examples/tutorials/ex27.c referenced in the Coffey paper.
Unfortunately, there is still a dangling reference from the TS example that needs to be fixed. Note that there is a slight mistake in the paper -- they describe the algorithm as linearly implicit but the numerical results were created using nonlinearly implicit Euler. The algorithm as described is more efficient and the default using TSPSEUDO in the TS example. If you want to reproduce the numerical results, you'll have to change the SNES to converge the nonlinear solve instead of just the first step.
