a trouble with Baron

GAMS
1

Hello people…

Does someone help me with a doubt?
I Have a MINLP (nonconvex, although the objective function as well the constraints are concave functions), I’m trying to solve this model with Baron v 12.7.7, but with a very small instance the solver tells me that it is infeasible, but I Know that is wrong, actually I have a optimal solution which I enter as inicial solution and the solver keeps reported infeasibility.
Any idea of the reason?
Thanks a lot in advance.

Try to run the model with ”Option Limrow = largenumer” and look at the equation listing. If your input point is not feasible it will be shown here and you can identify the equation where you have made a mistake.
