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.

DASSAULT SYSTEMES has decided not to be responsible for supporting and maintaining Java versions deployed by our installation media. The reasons for this are numerous, including the issue of having to manage and maintain patches due to security holes in various Java releases.

The changes mentioned in this article only affect 3DOrchestrate stations (public and private). This change does not affect 3DOrchestate Server deployments configured to use embedded Java for testing demonstration purposes.

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.

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.

This prototype includes modeling and simulation of a complete DDR5 interface. The passive channel (i.e. the PCB) is modeled with Altium. The IBIS models are created in Simulink.

The analog channel is simulated in CST and the AMI simulation is implemented in python.

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).

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.

Abaqus/CAE contains a built-in version of the Additive Manufacturing plug-in.  It is accessed by selecting Plug-ins → AM Modeler from the menu bar.

The AM plug-in (or AM Modeler) can be used to set up the thermal and mechanical models for the part-level sequential simulation of various AM processes, including SLM (Selective Laser Melting), LDED (Laser Direct Energy Deposition), and FFF (Fused Filament Fabrication).
