TSARKIMEX
ODE solver using Additive Runge-Kutta IMEX schemes These methods are intended for problems with well-separated time scales, especially when a slow scale is strongly
nonlinear such that it is expensive to solve with a fully implicit method. The user should provide the stiff part
of the equation using TSSetIFunction() and the non-stiff part with TSSetRHSFunction().
Notes
The default is TSARKIMEX2E, it can be changed with TSARKIMEXSetType() or -ts_arkimex_type
This method currently only works with ODE, for which the stiff part G(t,X,Xdot) has the form Xdot + Ghat(t,X).
