  • Solver directo usando múltiples GPGPUs: soporte para múltiples GPUs en el solver directo para mayor velocidad de ejecución en ordenadores con múltiples tarjetas GPU.
Fluid Analysis
  • Steady-state analysis
    • Steady-state flow problems can now be solved directly, eliminating the need to approximate steadystate conditions using a long-duration transient flow simulation.  This enhancement substantially improves overall computational performance in common stead-state CFD simulations.
  • SST k–ω turbulence model
    • The popular two-equation SST k–ω turbulence model can now be applied to fluid flow problems.
  • Hybrid wall functions
    • Both the Spalart-Allmaras and the new k–ω turbulence models now exhibit reduced sensitivity to the boundary layer mesh size
Heat Transfer
  • Thermal matrix output
    • You can now request thermal conductivity, heat capacity, and heat flux operator output in an Abaqus/Standard uncoupled heat transfer analysis. These operators can be used to construct an abstract representation of a finite element heat transfer model, for use with techniques such as model order reduction.
  • Uncoupled heat transfer in Abaqus/CFD
    • Abaqus/CFD’s high capacity, performance, and parallel scalability can now be used to run uncoupled solid heat transfer simulations
Crack Modeling and Propagation
  • XFEM enhancements
    • The XFEM method can now be extended to support the application of distributed pressure loads to the cracked element surfaces, which makes the analysis more realistic.
    • To reduce mesh dependence, you can specify where the stress/strain values are used to determine if the crack propagation criterion is satisfied.
  • Abaqus/CAE support for VCCT in Abaqus/Standard models
    • You can now use Abaqus/CAE to model crack propagation with Abaqus/Standard using the virtual crack closure technique (VCCT).
Contact Enhancements
  • Contact modeling for beams and shells
    • Beam-to-surface and beam-to-beam contact can now be modeled with general contact in Abaqus/Standard.
  • Convergence behavior for Abaqus/Standard
    • Intra-increment adaptivity of specific contact controls for Abaqus/Standard is provided based on the philosophy that the early iterations for a nonlinear implicit simulation increment should robustly find an approximate solution and subsequent iterations should fine-tune the solution to provide a high degree of accuracy.
    • The intra-increment adaptive contact controls are intended for advanced users and will likely undergo changes in subsequent releases of Abaqus/Standard.
  • Contact calculations for thick shells/beams in Abaqus/Explicit
    • Computation of the effect on contact results due to consideration of incremental rotation of thickness offsets for friction is now more accurate.
    • Frictional constraints apply a moment to reference nodes offset from the contact interface due to shell or beam thicknesses, to oppose the net moment associated with the frictional force couple.
  • Friction coefficient dependencies
    • You can define the friction coefficient as a function of temperature and field variables with the general contact algorithm in Abaqus/Explicit.
  • User-defined tracking thickness
    • You can now limit the contact search distance for contact pairs referring to user subroutine VUINTER to improve analysis efficiency in Abaqus/Explicit.
Linear Dynamics
  • Composite modal damping
    • Composite modal damping is available for eigenvalue extraction that uses the SIM-based Lanczos eigensolver.
    • You specify composite modal damping in the frequency extraction step definition, which is in contrast to analyses using the traditional architecture, where you specify composite modal damping in the material definition.
  • SIM Architecture support of Coupled Acoustic-Structural Eigenmodes
    • The coupled structural-acoustic eigenmodes extracted by the Lanczos eigensolver can be stored on the SIM architecture. In addition, subsequent modal methods can utilize these modes for superposition.
  • Contact pressure-dependent constrain enforcement in Perturbation steps
    • You can now relax or completely remove contact constraints on all points in contact (i.e., with a “closed” status) depending on the local base state contact pressure during linear perturbation steps in Abaqus/Standard.
Materials
  • Enhanced printed diagnostics for nearly incompressible materials
    • As an aid to convergence diagnosis, printed diagnostics have been enhanced in models with nearly incompressible materials.
  • Parallel rheological framework
    • The parallel rheological framework allows you to model the response of materials subjected to large strains that exhibit nonlinear time-dependent behaviors, such as polymers, accurately.  The model consists of multiple viscoelastic networks and, optionally, one elastoplastic network.
  • User-defined EOS
    • You can now use user subroutine VUEOS to define a hydrodynamic material model in which the material’s volumetric response is determined by your own definition of the equation of state.
  • Tabulated EOS in Abaqus/CAE
    • You can now create materials with tabulated equations of state linear in energy in Abaqus/CAE, which increases the coverage of Abaqus product functionality.
Meshing in Abaqus/CAE
  • Query for geometry without an associated mesh
    • You can now query for the cells, faces, edges, or vertices in your part or model that are not associated with a mesh making it easier to complete meshing before you submit an analysis.
  • Copy a mesh pattern
    • You can now copy a two-dimensional pattern of element faces onto a similar geometric face.
  • Enhanced mesh quality options
    • The Verify Mesh dialog box now provides access to a wider range of options for verifying mesh element quality.
