Is it possible to help with the development of solver? If non linear solutions are so common and stable now, what would be the difficulty to program it into Openoffice? Please send info regarding how to program new functions in Openoffice to have a go at programing my own solver.
To be honest, I’m not sure that I understand your request correctly.

Please clarify your request, what is your desired goal and what do you mean by ‘programing my own solver’?
