    Hi João,

    You can see from the logs that Gurobi is struggling to find a feasible solution (maybe this model is even infeasible).  Here are a couple of things to try:

    * set the objective to 0, so that you are solving a feasibility problem
    * try our No Relaxation heuristic by setting NoRelHeurTime to a large number.  Phase 1 is the heuristic trying to find a feasible solution.
    * run with different values of Seed - perhaps another "solution path" will have more success
