A defect is Potentially Serious when one behavior should occur, but the software is providing a wrong result or behavior that is not obvious to the user.  A defect is classified as Potentially Serious without regard for the frequency at which it may occur.

This article includes a spreadsheet listing of the SIMULIA potentially serious errors.

A plug-in is a piece of software that installs itself into another application to extend the capabilities of that application. Abaqus plug-ins execute Abaqus Scripting Interface and Abaqus GUI Toolkit commands, and they provide a way to customize Abaqus/CAE for your particular needs or preferences.

Several plug-ins are provided on the Abaqus installation CD. The portal provides example plug-ins as well as access to a community of users that fosters the advance of the Abaqus Scripting Interface and the Abaqus GUI Toolkit. You can also write your own plug-ins.

GPGPU direct solver acceleration is supported in Abaqus 6.11 and later. The direct sparse solver in Abaqus/Standard can use compute-capable GPGPU cards to reduce the run time for equation solution. High-end graphics cards that support general processing (GPGPUs) offer an additional way to improve performance of compute-intensive applications.

The tested GPGPU graphics devices are listed on the SIMULIA System Requirements pages.  Other GPGPU devices can be used as long as they support compute capability level 2.0 or higher.

CST Bio Models Library Extension is a collection of add-on human body models, phantoms, macros and materials extending the CST Bio Models Library for bio-electromagnetics, bio-medical and high-tech applications like implants, body-worn or mobile devices or medical imaging.

It needs to be downloaded and installed separately from the CST Studio Suite(R).

When it comes to deleting simulation data from the 3DEXPERIENCE platform, there are certain do's and don'ts that one should keep in mind. Following these best practices can help you avoid leaving orphaned simulation results and ensure that your data is properly managed.

This article explains the recommended steps to delete both simulation objects and their results from 3DEXPERIENCE Cloud.

Batch queuing systems are designed to manage applications and compute resources, while maximizing the usage of each. Often each system is customized for a company's needs, according to available computing resources and applications supported.

This article explains a way to run Abaqus analyses using a resource manager batch queue.

Please see the SIMULIA Platforms & Configuration Support page for additional information on performance test data and detailed descriptions of the benchmark models. Select the link for the release of interest, and then select the link to the performance data.

Environment set-up consists primarily of assigning proper values to memory management parameters in the abaqus_v6.env file. There are no environment file parameters that control memory use by Abaqus/Explicit (explicit.exe) and the Abaqus/Explicit packager (package.exe). The default memory value is usually sufficient for most systems.

This article gives you detailed instructions for installing and updating the SIMULIA CST Studio Suite license server for the supported operating systems. The process for updating the license server is the same as installing the license server.

It is recommended that you install CST License Server on Windows or Linux by using the latest release of SIMULIA CST Studio Suite installation package. During the installation process, select the “License Server only” setup type.

DSLS has been introduced for the first time in CST Studio Suite with CST 2021, i.e. CST 2021 and onwards has an option to select either FlexLM or DSLS.

Please note that the license files for FlexLM and DSLS license services are not compatible, i.e. license files issued for FlexLM cannot be used with DSLS and vice versa.

This article explains a few general questions about using the on premise CST Studio Suite with an on premise DSLS.

Sometimes an Abaqus/Standard analysis and the message file contains warnings about negative eigenvalues.

Negative eigenvalue messages are generated during the solution process when the system matrix is being decomposed. The messages can be issued for a variety of reasons, some associated with the physics of the model and others associated with numerical issues.

This article discusses about the meaning and causes of such warnings.
