Application of Improved Truncation Error Estimation Techniques to Adjoint Based Error Estimation and Grid Adaptation
… Dynamics (CFD) are subject to discretization error, which is locally generated by truncation error. The discretization error is extremely difficult to properly estimate and this in turn leads to uncertainty over the quality of the numerical solutions obtained via CFD methods and the …

Residual-based Discretization Error Estimation for Computational Fluid Dynamics
… and most difficult numerical approximation error to estimate is discretization error. Residual-based discretization error estimation methods are a category of error estimators that use an estimate of the source of discretization error and information about the specific application to …

PARASPICE: A parallel direct circuit simulator for shared-memory multiprocessors
… of sparse linear systems (SOLVE), and local truncation error estimation (TRUNC), which account for at least 95 percent of the total job time. Therefore, it is suitable for a wide range of shared-memory multiprocessors. The implementation of the approach in SPICE2 resulted in a portable …

Discretization Error Estimation Using the Error Transport Equations for Computational Fluid Dynamics Simulations
… methods, and finite-element methods. Error introduced in the discretization process is called discretization error and defined as the difference between the exact solution to the discrete equations and the exact solution to the partial differential or integral equations. For most CFD …

On Numerical Error Estimation for the Finite-Volume Method with an Application to Computational Fluid Dynamics
… each CFD result inherently contains numerical errors that can significantly degrade the accuracy of a simulation. Discretization error is typically the largest contributor to the overall numerical error in a given simulation. Discretization error can be very difficult to estimate since the …
