[GAMSlinks] IPOPT options through GAMS

[Susana Lera]

hi,

I am trying to run a nonlinear problem with IPOPT through GAMS.
I made a ipopt.opt file where I write my ipopt options. I tried to save this file in several locations, but it is never recognize by GAMS.

Does anybody know where the right location for the file is? and whether this is the right file name and extension for defining the options?

Thanks.
Susana
