The Numerical Uncertainty Analysis tools can be used to determine the iterative error, and the order of accuracy and numerical uncertainty from a number of grids, and time-steps for different variables. The analysis is mainly based on the procedures by Eça and Hoekstra (2014) and Eça et al. (2019). Two tools are available, one to estimate the iterative error, and one to estimate the discretisation uncertainty.

The tools can be downloaded with the buttons below. The package contains a user manual, a set of papers regarding verification and validation and examples to run the tools.

Please acknowledge the usage of these tools by citing this page or/and any of the papers in the package.
