How to minimize cost function define over volume omega using BFGS algorithm?

[Lemine]

Hello Mechanical engineers,

I have computed a cost function J(x1,..xn) and her gradient J'(x1,..xn) defined over a volume using finite element analysis.
so I have the value of these fields J and J' at n nodes (x1,..xn) in the geometry (integration point) and I have saved the data in a text file.
My problem is how to minimize this function using for example BFGS algorithm?

Thanks for your help
