Structural adhesives are widely used in aerospace, automotive, electronics, and life science applications due to their corrosion resistance, lightweight design, and clean bonding characteristics. However, the curing process, where a liquid adhesive transforms into a solid, introduces complex thermal and chemical effects. These effects can generate residual stresses that compromise the strength and durability of bonded assemblies if not properly accounted for.  In this blog, w

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

Visualizing flow behavior over an airfoil using PowerFLOW streamlines Laminar separation is a critical aerodynamic and acoustic challenge in low-Reynolds-number flows, like those found in eVTOL rotors and wind turbine blades. Historically, this transition from laminar to turbulent flow was hard to simulate accurately and required manual workarounds. With recent improvements in PowerFLOW, it’s now possible to capture these effects directly and reliably.  Why Laminar Separation

Noise control is a growing priority across industries ,  from aerospace and automotive to consumer electronics and renewable energy. SIMULIA PowerFLOW offers advanced aeroacoustic simulation capabilities, allowing engineers to predict and reduce flow-induced noise early in the design process. This leads to quieter, more efficient products, shorter development cycles, and fewer costly design iterations.  Why SIMULIA PowerFLOW?  Built on the lattice-Boltzmann method (LBM) and V

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
