Analysis and performance

GPU acceleration and dynamics workflows

Performance improvements target time to solution, especially 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: run 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 supports most features, with exceptions including user subroutines, CEL, ALE, and particle methods
The figure below shows example speedups across several Abaqus/Explicit benchmarks when adding 1 GPU and 2 GPUs, highlighting differences between element computation dominated and contact dominated workloads.

SPH liquid modeling updates

SPH performance and memory usage are improved for liquid modeling by changing how particle interactions are computed.

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 is improved to reduce idle time and make better use of available processors.

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 support expands, with one important behavioral change to keep in mind for cut surfaces.

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 expands fatigue crack growth capability with a more automated 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 improvements broaden contact driven workflows across Standard and 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 as seen in the figure below

Keywords and input file updates

Several keyword enhancements expand control, output targeting, and analysis setup. A few notable changes in Abaqus Keywords include:

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
