Preface
This section lists various resources that are available for help with using Abaqus Unified FEA software.
Support
Both technical software support (for problems with creating a model or performing an analysis) and systems
support (for installation, licensing, and hardware-related problems) for Abaqus are offered through a global
network of support offices, as well as through our online support system. Regional contact information is
accessible from the Locations page at www.3ds.com/simulia. The online support system is accessible from
the Support page at www.3ds.com/simulia.
Online support
SIMULIA provides a knowledge database of answers and solutions to questions that we have answered, as
well as guidelines on how to use Abaqus, SIMULIA Scenario Definition, Isight, and other SIMULIA products.
The knowledge database is available from the Support page at www.3ds.com/simulia.
By using the online support system, you can also submit new requests for support. All support incidents
are tracked. If you contact us by means outside the system to discuss an existing support problem and you
know the support request number, please mention it so that we can query the database to see what the latest
action has been.
Anonymous ftp site
To facilitate data transfer with SIMULIA, an anonymous ftp account is available at ftp.simulia.com.
Login as user anonymous, and type your e-mail address as your password. Contact support before placing
files on the site.
Training
All support offices offer regularly scheduled public training classes. The courses are offered in a traditional
classroom form and via the Web. We also provide training seminars at customer sites. All training classes
and seminars include workshops to provide as much practical experience with Abaqus as possible. For a
schedule and descriptions of available classes, see the Training page at www.3ds.com/simulia or call your
support office.
Feedback
We welcome any suggestions for improvements to Abaqus software, the support program, or documentation.
We will ensure that any enhancement requests you make are considered for future releases. If you wish to
make a suggestion about the service or products, refer to www.3ds.com/simulia. Complaints should be made
by contacting your support office or by visiting the Quality Assurance page at www.3ds.com/simulia.
