Dear Dr. Zimmerman, Thanks a lot for your help.
I want to minimize the cost of generation of one area subject to a fixed value for the exchange between all the other areas. Shall I still work with toggle_iflims.m as you suggested or you have some other suggestions? Thanks a lot.

If so, the best you can do is constrain the net flow (DC > approximation) to equal your specified value.
