ODE and DAE 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 <A HREF="../TS/TSSetIFunction.html#TSSetIFunction">TSSetIFunction</A>() and the non-stiff part with <A HREF="../TS/TSSetRHSFunction.html#TSSetRHSFunction">TSSetRHSFunction</A>().
<P>
<H3><FONT COLOR="#CC3333">Notes</FONT></H3>
The default is <A HREF="../TS/TSARKIMEX3.html#TSARKIMEX3">TSARKIMEX3</A>, it can be changed with <A HREF="../TS/TSARKIMEXSetType.html#TSARKIMEXSetType">TSARKIMEXSetType</A>() or -ts_arkimex_type
<P>
If the equation is implicit or a DAE, then <A HREF="../TS/TSSetEquationType.html#TSSetEquationType">TSSetEquationType</A>() needs to be set accordingly. Refer to the manual for further information.
<P>
Methods with an explicit stage can only be used with ODE in which the stiff part G(t,X,Xdot) has the form Xdot + Ghat(t,X).
<P>
Consider trying <A HREF="../TS/TSROSW.html#TSROSW">TSROSW</A> if the stiff part is linear or weakly nonlinear.
