The Fluid Dynamics Verification Manual presents a collection of test cases that demonstrate a representative set of the capabilities of the ANSYS Fluid Dynamics product suite. The primary purpose of this manual is to demonstrate a wide range of capabilities in straightforward problems that have "classical" or readily-obtainable theoretical solutions and in some cases have experimental data for comparison. The close agreement of the ANSYS solutions to the theoretical or experimental results in this manual is intended to provide user confidence in the ANSYS solutions. These problems may then serve as the basis for your additional validation and qualification of ANSYS capabilities for specific applications that may be of interest to you.

Although these test cases allow comparison against theoretical solutions and experimental data, we have selected relatively simple problems that run quickly and can be conveniently used to test for consistency across multiple platforms. They are not intended to provide a rigorous validation of the model, which generally requires a greater number of much longer running problems. This manual represents a small subset of the Quality Assurance test case library that is used in full when testing new versions of Ansys Fluent, Ansys CFX, and Ansys Forte. Furthermore, because these programs are capable of solving very complicated practical engineering problems that have no closed-form theoretical solutions, the test cases in this manual do not illustrate their full capability.

The Ansys software suite is continually being verified by the developers at ANSYS as new capabilities are added to the software. Verification of Ansys products is conducted in accordance with written procedures that form a part of an overall Quality Assurance program at Ansys.
