Abstract
In this study, we present a new numerical method to quantitatively analyze the error of numerical solutions by using the adjoint sensitivity analysis. If a reference case of typical parameter is once calculated with the method, no additional calculation is required to estimate the results of the other numerical parameters such as more detailed solutions. Furthermore, we can estimate the exact solution from the results and can quantitatively evaluate the numerical error. To confirm the effectiveness of the method, we consider here a two-dimensional pure advection problem.
