ODE solver suite

Question

Hi,

FEniCS used to have an ODE solver, which has since been removed. However, I seem to recall someone remarking that it'll be re-added.

If it has, are there examples/tutorials I can read to understand how to use it?
If it hasn't, are there still plans to re-develop it?

Thanks.

Answer 1

There are some preliminary work on a general Runge Kutta framework. It is developed to solve vectorized ODEs on vertices. Think reaction equations integrated with a point integral at each vertex. The development is done in the branch johanhake/mutistage. It includes some examples in the unit test:

Thanks Johan, I'll check it out.
