The scheme is based on the sample point error analysis and the extended error indicator, proposed initially by the present authors for the potential and elastostatic problems and extended successfully to multidomain and thermo-elastic analysis. Since the field variable is connected with its derivative on the boundary, their errors are also interconnected by the specified condition. The extended error indicator on each boundary element is modified to meet
