Detailed modelling of piezoelastic structures often includes also an external circuit. This is tied with the need for a weak imposition of electric potential Dirichlet boundary conditions and questions of simulation accuracy arise. Several methods allowing the weak imposition, namely the non-symmetric Nitsche’s method, penalty method and their combinations, are evaluated and their numerical convergence w.r.t. uniform mesh refinement for various finite element approximation orders is reported. The numerical study is performed on a geometry corresponding to a piezoelectric sensor.
