Meshed abacus model in Abaqus, representing cost-effective nonlinear simulation. Unlocking Full Simulation Power Without Complexity When choosing a simulation tool, it's not just about performance – accessibility and licensing flexibility matter just as much. Engineers often face fragmented systems that require multiple licenses to unlock advanced features. This not only increases costs but also complicates workflows. Abaqus stands out by removing these barriers. With a sing

Access updates, fixes, and documentation via the Abaqus program directories Keeping your Abaqus installation up to date is essential, especially when working with nonlinear, multiphysics, or large-scale models. Dassault Systèmes provides a centralized location for all update and release-related content: the Abaqus program directories .  These directories go beyond software packages. They include deployment tools, licensing information, known issues, and version-specific docum

Visual Studio 2022: Select 'Desktop development with C++' and required components Why a Fortran Compiler is Needed for Abaqus Abaqus provides robust built-in capabilities, but many users extend its functionality using user subroutines written in Fortran. These subroutines allow you to define custom material behavior, loads, boundary conditions, and more. To use them, however, you need a compatible Fortran compiler. Fortunately, a free and compatible solution is now available:

Custom scripts are often key to advanced simulations. We provide expert support. Advanced simulation requires more than just installing the software. For teams working with nonlinear models, subroutines, and complex workflows, expert support plays a critical role in ensuring success. Whether you're solving convergence issues or preparing for a major release update, having a trusted partner by your side can accelerate development, reduce errors, and increase confidence in your

Fiber-driven stress patterns in arterial tissue simulation with Abaqus. Modeling Anisotropic Hyperelasticity in Abaqus  Many modern materials, from fiber-reinforced elastomers to soft biological tissues, exhibit direction-dependent, nonlinear elastic behavior. These materials don’t deform uniformly; instead, their mechanical response varies along preferred directions and becomes increasingly complex under large strains.    Simulating these effects accurately requires more...

Airbag inflation modeled with large deformation simulation in Abaqus. Many real-world engineering challenges involve large and irreversible shape changes. Think of crushed vehicles, stretched polymers, or deformed metal sheets. Simulating such extreme strain behavior requires powerful and reliable tools. Abaqus stands out with its ability to handle severe geometric and material nonlinearities while maintaining stability and accuracy. In this post, we explore how Abaqus enable

Start screen of Abaqus/CAE 2025 after successful installation. Installing Abaqus 2025 involves several detailed steps, from downloading the correct media to configuring license settings and optional components like Isight and Tosca. This step-by-step guide helps ensure a smooth and complete installation process across supported systems. Before You Start  This installation manual assumes that the license server is already operational.  Ensure the SIMULIA license server is alre

Start screen of Abaqus 2023 with updated interface and new feature access. The Abaqus 2023 release brings a wide set of usability, performance, and modeling  improvements, particularly for coupled multiphysics, nonlinear materials, and dynamic analyses. Many of the enhancements originally introduced via 2022 Fix Packs are now part of the core release.   This post summarizes the most relevant changes for engineering workflows across CAE, materials, solvers, substructures, and

Reduce file size using Compress MDB in Abaqus/CAE Sharing finite element models with colleagues or clients often involves sending large Abaqus/CAE (.cae) files. These files can grow substantially during model development, especially as geometry, mesh, and output data accumulate. Fortunately, Abaqus includes a built-in tool that allows you to compress CAE files without losing essential data, making them easier to store and transfer.  The Challenge: Large CAE Files in Collabora

What’s New in Abaqus 2025? Highlights in Modeling, Performance, and Multiphysics   The Abaqus 2025 general availability (GA) release, along with the first five Fix Pack (FD) updates of Abaqus 2024, introduces powerful new capabilities across modeling, solver performance, material behavior, and co-simulation. These enhancements offer analysts and engineers increased modeling flexibility, faster simulation runtimes, and new physics-driven features for advanced applications in f

This blog highlights part of the PhD work of our colleague Elmer, conducted at Eindhoven University of Technology , where simulation met mechanobiology to explore one of the most ambitious applications of engineering tools: living heart valve replacements.  Heart valve disease often requires surgical intervention. While current prosthetic valves can restore blood flow, they are non-living and cannot grow or adapt, posing a major limitation, especially for younger patients. Th

The DS License Server is a central licensing solution developed by Dassault Systèmes for managing product licenses such as SIMULIA Abaqus, CATIA, DELMIA, and ENOVIA. The licensing setup relies on generating a Computer ID from the target system using the DSLicTarget tool. This guide explains how to use DSLicTarget effectively, with details on command options and typical usage.   Download DSLicTarget.exe here!  Command Options and Descriptions  1.

Problem   When using Abaqus/CAE for job submissions, engineers occasionally face a confusing situation: a job appears stuck at the “submitted” state in the model tree, even though it is running perfectly well in the background. This disconnection between the CAE interface and the job execution process can disrupt workflows and make it difficult to track simulation progress.  This issue is frequently accompanied by a warning in the job's log file:  * **WARNING: Interactive mes

What's New in Abaqus 2024: Targeted Improvements for Advanced Simulation Workflows  The Abaqus 2024 General Availability (GA) release introduces a curated set of enhancements across structural mechanics, materials, battery modeling, contact behavior, design sensitivity, and automation. Many of these features were developed in Fix Packs throughout the Abaqus 2023 cycle and are now consolidated for full release.  This post outlines the most impactful updates with relevance to e
