چکیده مقاله
An error indicator of the discrete least squares method DLSM for 2D elastostatic problems is presented In the DLSM, the problem domain is discretized by distributed field nodes The field nodes are used to construct the trial functions The moving least squares interpolant is employed to construct the trial functions The least squares technique is used to obtain the solution of the problem by minimizing the summation of the residuals for the field nodes The error indicator is readily computed from the residual of the governing differential equation It is demonstrated, through some elastostatic problems, that the error indicator reflects the exact error
