Overview

Abaqus 2026 FD01 shortens simulation turnaround through GPU acceleration, opens more of the multiphysics setup to the GUI, and tidies up daily modeling work. The main areas are:

GPU acceleration is now supported in Abaqus/Explicit on NVIDIA GPUs for Linux, across a wide range of dynamic and quasi-static structural simulations
More GUI coverage for coupled thermal electrochemical workflows and the related fields, loads and boundary conditions, which the keywords editor used to handle alone
Expanded contact and interaction setup options, including electrical and thermal contact property enhancements
Usability improvements in Abaqus/CAE for geometry creation, visualization, and job execution

The rest of this article goes through the release in the order an Abaqus job is built and run.

Modeling and preprocessing

Documentation and model organization

Two small changes make the documentation and the model tree easier to work with.

PDF versions of the Abaqus documentation guides are available from each guide overview. They update with every HTML documentation release, including the ones between GA releases
A node set can be generated directly from a surface defined earlier, which makes surface based selection more direct

Abaqus/CAE productivity and visualization

Geometry and datum tools

Common reference geometry can now be created directly in the GUI, so model setup takes fewer construction steps.

New datum point, axis, and coordinate system creation methods, including coordinate based points, axis plane intersections, cross product axes, projection axes, and rotated coordinate systems
Improved AutoCAD DXF sketch import with support for polylines, splines, ellipses, and other complex entities
Seam creation is supported on dependent part instances for fracture modeling workflows

Sections, profiles, and display options

These changes cover repetitive setup tasks and make results easier to read.

Channel and hat beam profiles can be defined directly in the Property module
Continuum particle element plots support multiple render styles to better distinguish particle based regions
Animations can be saved and loaded as MP4 or animated GIF for easier sharing and presentation

Multiphysics setup in the GUI

Coupled thermal electrochemical modeling is easier to set up, since the fields, loads and constraints now sit in Abaqus/CAE itself alongside the keywords editor.

Predefined fields for fluid electric potential, solid electric potential, and ion concentration
Boundary conditions for electric potential electrolyte and ion concentration
Loads for distributed ion concentration body flux, ion concentration flux, and fluid surface current
Tie constraints can include additional degrees of freedom such as temperature, pore pressure, and electrochemical degrees of freedom
Uniform coupling type can be used to couple non displacement degrees of freedom
GUI support for coupled thermal electrochemical procedures, including structural and structural pore pressure variants

Contact, thermal interactions, and step controls in the GUI

Contact and step definition have broader GUI coverage, above all where contact combines with thermal and electrochemical behavior.

Surface film and surface radiation can be defined on evolving faces of elements
Gap diffusivity contact property is supported in the GUI
Gap electrical conductance contact options expanded, including solid and liquid electrolyte behavior and ion concentration dependent data for liquid electrolyte
Gap heat generation contact options expanded, including multiple interaction fractions and weighting factors
Step controls can be defined and modified in the GUI
Follower parameter support for pre tension sections helps large displacement bolt load setups
Contact mass scaling can be defined for Abaqus/Explicit simulations

Execution and scripting foundations

Platform and scripting updates change how jobs are launched and automated.

Job execution can use 3DEXPERIENCE® on cloud licensing when launching Abaqus/CAE from the Platform Connector
Abaqus Python and Abaqus/CAE are based on Python 3.10. For more information about this major change, visit go.3ds.com/AbaqusPython

Analysis and performance

GPU acceleration and dynamics workflows

These changes cut time to solution, above all for large explicit models and dynamic workflows.

Abaqus/Explicit supports execution on GPU devices and shows that performance gains are workflow dependent but can be significant for large models, especially models with hundreds of thousands up to multiple millions of elements
Flexible execution options, on a single node with one or more GPUs, or on a multi node cluster with multiple GPUs
Fourier transform support in linear dynamics procedures enables time domain and frequency domain conversions within modal based workflows
GPU execution covers most features, leaving out user subroutines, CEL, ALE, and particle methods
The figure gives the speedup across several Abaqus/Explicit benchmarks with one GPU and with two GPUs, and element computation dominated workloads gain more than contact dominated ones

SPH liquid modeling updates

A change in how particle interactions are computed improves SPH performance and memory use for liquid modeling.

New particle to particle pairwise interaction algorithm improves performance and reduces memory usage for SPH simulations in liquids

Co-simulation and field mapping scalability

Co-simulation mapping uses the available processors better, so each partner spends less time idle.

Mapper neighborhood search and mapping during field transfer show significant speedup when more processors are engaged, reducing partner idle time during co simulation

Submodeling enhancements and behavior changes

General submodeling covers more combinations, and one behavior on cut surfaces changes with it.

General submodeling supports beam-to-beam and solid-to-solid submodeling in addition to existing combinations, including additional degrees of freedom such as temperature and pore pressure
Submodel cut surface definition is moved from history data to model data, and submodel conditions must be applied to all primary degrees of freedom on the cut surface

Fracture and fatigue

Abaqus/Standard automates more of the fatigue crack growth workflow.

Fatigue crack growth with adaptive remeshing is available in Abaqus/Standard for linear elastic crack growth under cyclic loading

Interactions and contact behavior

Wear modeling and contact usability changes broaden contact driven workflows across Abaqus/Standard and Abaqus/Explicit.

Wear modeling is supported in Abaqus/Standard and Abaqus/Explicit using Archard wear formulation, with nodal wear distance visualization
In steady state transport analyses, surface wear properties can be specified directly and Abaqus/Standard computes wear rate and total wear distance output
Reference thread geometry in Abaqus/Standard can be specified on either surface of a small sliding general contact interaction for better usability
Contact surface representation for beams and pipes is improved, including more realistic contact treatment for noncircular beam cross sections and configurable surface element generation for circular sections. The figure gives the surface elements generated for each cross section

Keywords and input file updates

Keyword changes expand control, output targeting and analysis setup. Among them:

Contact controls assignment supports additional TYPE values including enforcement method, friction enforcement, permeability constraint method, and tracking thickness
Controls option can adjust default contact and slip compatibility tolerances when using specific converge check settings
Step cycling and step cycling control options add repeated step capability with early termination criteria
Electrical conductivity coverage is extended to coupled thermal electrochemical families, and electrical resistivity is introduced for workflows such as piezoresistive materials
Surface film transition parameter adds control of film coefficient dependence on contact status, and step control tolerance parameter adds clearer threshold triggering behavior
Surface section can define constant thickness surface elements independent of rebar usage, and wear surface properties activates wear distance accumulation at contact nodes
Node output can target a named surface using a new surface parameter

Materials updates

The material library grows across fabrics and composites, rubberlike behavior, polymer creep and softening, damping, porous media, and coupled electromechanical effects.

Composites, fabrics, and orthotropic behavior

Ply fabric material model is available in Abaqus/Standard for bidirectional fabric reinforced composites, using a multilayer homogenization approach and supporting inelastic behavior in the thickness direction. Result import is supported between Abaqus/Standard and Abaqus/Explicit.
Paperboard material model is available in Abaqus/Standard and Abaqus/Explicit, aimed at highly orthotropic paperboard workflows including plasticity effects.
Plane stress orthotropic failure measures add a new stress-based measure based on the Yamada Sun theory.

Damage and failure modeling

Generalized damage initiation criteria are added for fully anisotropic materials, with stress based and strain-based criteria available broadly across material types and stress displacement elements.
Multiscale damage and failure for fiber reinforced composites adds new micro level failure criteria based on stress invariants and supports damage evolution, with support extended to 3D elements.

Hyperelastic and rubberlike behavior

Hencky hyperelastic model is available to define elastic response for moderately large deformations, and can serve as a finite strain alternative to isotropic linear elasticity in cyclic loading cases.
Hencky hyperelastic behavior is now supported in Abaqus/Explicit, including results transfer between Abaqus/Standard and Abaqus/Explicit.

Creep and softening in the parallel rheological framework

Viscous softening is supported for nonlinear viscoelastic networks in the parallel rheological framework in Abaqus/Standard and Abaqus/Explicit.
Anand creep model is now available in the parallel rheological framework in Abaqus/Standard and Abaqus/Explicit.
Darveaux viscous behavior can be used in the parallel rheological framework to capture both primary and secondary creep.
Modified Darveaux viscous behavior stays stable when a step includes idle time or periods of zero loading.

Cure and process driven behavior

Ductile damage initiation criteria can now be computed for hyperelastic materials with isotropic plasticity, supporting efficient preload in Abaqus/Standard before continuing degradation in Abaqus/Explicit.
Kamal cure model coefficients can now depend on temperature and field variables, expanding cure modeling workflows where external drivers such as ultraviolet radiation influence curing.

Porous media and damping

Field expansion can now be defined independently for solid grains and pore fluid in porous media, and pore fluid expansion and strain outputs are supported.
Frequency dependent structural damping is supported in Abaqus/Standard, and damping definitions can depend on field variables across alpha, beta, band limited, and structural damping.
Band limited damping adds an option to keep damping ratio approximately constant within a specified frequency band for implicit dynamics.

Electro mechanical coupling

Piezoresistive effect can be modeled in Abaqus/Standard for materials whose electrical resistivity changes with stress.
Electrical resistivity can now be defined directly in Abaqus/Standard, which also supports piezoresistive workflows.

Conclusion

Abaqus 2026 FD01 widens what the GUI covers and improves the solver and the workflow around it, which cuts setup time and turnaround on large and multiphysics models. Teams running battery electrochemical work, contact heavy simulations and dynamic analysis pipelines get the most out of this release.

GPU acceleration is the change with the largest effect on big Abaqus/Explicit models, and the gains are widest where element computation dominates the run. The same job scales from one workstation with a single GPU up to a multi node GPU cluster, so a model that outgrows the desk keeps the same setup on an HPC queue.

Further releases follow through the year, and we cover each one here.
