AbstractIn this study a special transformation is used to develop a new recovery patch errorestimator For validation the estimator is applied to heat transfer and elasticity problems The displacement and temperature functions in elasticity and heat transfer problems respectively are approximated by a complete polynomial satisfying the differentialequations governing the problem as well as a series of exponential functions to calculatethe improved values of displacements and thermal variation through the recoveryprocedure These values are then used to determine the values of improved gradients Theefficiency of the proposed method has been established by a case study and comparedwith SPR and REP0 methods In these comparisons the value and the rate of the totalerror convergence have been compared with those of the error at a mid point of domain
