Overview
AIM Test Cases
Index of Test Cases
Overview
This manual presents a collection of test cases that demonstrate a number of the capabilities of the
Workbench analysis environment.The available tests are engineering problems that provide independent
verification, usually a closed form equation. Many of them are classical engineering problems.
The solutions for the test cases have been verified, however, certain differences may exist with regard
to the references.These differences have been examined and are considered acceptable.The workbench
analyses employ a balance between accuracy and solution time. Improved results can be obtained in
some cases by employing a more refined finite element mesh but requires longer solution times. For
the tests, an error rate of 3% or less has been the goal.
These tests using Microsoft Windows 7 Enterprise 64-bit .These results are reported in the test docu-
mentation. Slightly different results may be obtained when different processor types or operating systems
are used.
The tests contained in this manual are a partial subset of the full set of tests that are run by ANSYS
developers to ensure a high degree of quality for the Workbench product.The verification of the
Workbench product is conducted in accordance with the written procedures that form a part of an
overall Quality Assurance program at ANSYS, Inc.
You are encouraged to use these tests as starting points when exploring new Workbench features.
Geometries, material properties, loads, and output results can easily be changed and the solution re-
peated. As a result, the tests offer a quick introduction to new features with which you may be unfamil-
iar.
Some test cases will require different licenses, such as DesignModeler, Emag, or Design Exploration. If
you do not have the available licenses, you may not be able to reproduce the results.The Educational
version of Workbench should be able to solve most of these tests. License limitations are not applicable
to Workbench Education version but problem size may restrict the solution of some of the tests.
The archive files for each of the Verification Manual tests are available at the Customer Portal. Download
the ANSYS Workbench Verification Manual Archive Files.These zipped archives provide all of the necessary
elements for running a test, including geometry parts, material files, and workbench databases.To open
a test case in Workbench, locate the archive and import it into Workbench.
You can use these tests to verify that your hardware is executing the ANSYS Workbench tests correctly.
The results in the databases can be cleared and the tests solved multiple times.The test results should
be checked against the verified results in the documentation for each test.
