This paper presents application and tuning of the equilibrated residual method (ERM) of
a posteriori error estimation for coupled electromechanical problems of direct, inverse and
general piezoelectricity. In these three cases, either electric potential is induced by strains or
strains appear due to the applied electric potential or both phenomena occur simultaneously.
The mentioned ERM is assigned for the assessment of modeling and approximation errors of
the numerical finite element solution. Such error values usually serve as indication for adaptive
hierarchical modeling and adaptive mesh changes within thin and/or solid piezoelectric
members so as to obtain the solution of assumed accuracy.
