Enforce a solution to see which constraints broke?

I currently have a model that 'should' always return a feasible solution, albeit it may be a bad one with high objective value (the task is to minimize the objective). For debugging purposes, is there a way to manually enforce a solution to the model to see which constraints would break?

  I am not sure I understand: if the solution violates the constraints it is not feasible anymore, isn't it?

  However, you can fix the upper and lower bounds of your variables to the values of the solution and then use feasRelax() or computeIIS() to compute the infeasibilities on that model. Please also see here for more details.
