## Chapter 6: CFX Best Practices Guide for Numerical Accuracy

This guide provides best practice guidelines for Computational Fluid Dynamics (CFD) simulation and documentation of the verification, validation, and demonstration test cases. It describes:

- An Approach to Error Identification, Estimation and Validation

- Definition of Errors in CFD Simulations

- General Best Practice Guidelines

- Selection and Evaluation of Experimental Data

This guide is aimed at users who have moderate or little experience using ANSYS CFX. It is part of a series that provides advice for using ANSYS CFX in specific engineering application areas. The current guidelines are adapted from Best Practice Guidelines developed for the nuclear reactor safety applications [143].
