 Hi Pietro

 Thank you very much for your answer. Unfortunately, this didn't solve the
 problem. I put a simplified version of the model and the input file in the
 attachment. The variables that are causing the problem call m.a_dir and
 m.p_dir. When I specify them manually as Parameters ipopt and couenne give
 me a result, so there should be a solution that is feasible. I hope that
 we can solve this
