[Ipopt] Managing large simulation codes

Hello
I want to use ipopt to optimize using a large Computational Fluid Dynamics
code. The situation can be described as follows
x = design variable
Flow solution:
Q = CFD(x)
Objective and constraint:
F = F(x,Q)
G = G(x,Q)
To obtain gradients of objective and constraint, I have to run two adjoint
solvers (assuming only one obj and one constraint)
F_x = CFD_F(x,Q)
G_x = CFD_G(x,Q)
All the solvers CFD, CFD_F and CFD_G are expensive.
My question is:
How would I manage these things so that I do not do any duplicate
computations ?
Q is too large and cannot be stored in memory.
Thanks
praveen
