This work introduces a general procedure to control (globally or in a goal-oriented way) the accuracy of simulation models used in Computational Mechanics. This procedure, which is based on the Constitutive Relation Error, provides for guaranteed and high quality bounds on the discretization error for a large panel of Mechanical Engineering models solved by approximate methods. It also enables to assess modeling errors which are generated in model reduction methods using reduced bases.
