Dear All,

I have just implemented root-finding operations of a function f(x) = 0. If someone is interested, have a look at the SVN - it currently lives in the ODE library.

Enjoy,

Hihttp://www.cfd-online.com/OpenFOAM_D...part/happy.gif

I am about to be solving 4 sets of non-linear equations on each face on certain boundary-patches. As far as I can see, the function implemented by Hrv is for 1 equation!?!
Is there anywhere in OF implemented some kind of solver for N non-linear set of equations?
If not, could you please suggest to me a suitable open-source implementation, preferable in C++.

Best regards,

Niels

P.S. Thank you for an utterly fantastic workshop.
