| Title: |
An estimation of the sensitivity of numerical error norm using adjoint model |
| Abstract: |
A posteriori estimation of the numerical error sensitivity to the local truncation error is addressed using
adjoint model endowed with the information on the error field. The numerical error is estimated from the
solution of the linear tangent model (LTM) or from a Richardson extrapolation. The local truncation error
used in the LTM is obtained by the action of a high-order finite-difference stencil on the field computed
by the main (low-order accuracy) algorithm.
