    • You can now specify translation, rotation, and reflection transformations to define the position of a matrix subassembly
    • Several enhancements to the steady-state transport inertia loading functionality provide more control over the convergence characteristics at high rolling speeds and simulation run time

  • Interactions (Enhanced Functionality)
    • Abaqus/Standard has improved accuracy and convergence behavior for stiff, permanent cohesive bonds within general contact for edge-to-surface and vertex-to-surface contact approaches
    • Damage initiation and damage evolution criteria can be defined as tabular functions of the effective rate of separation for surface-based cohesive behavior in Abaqus/Explicit
    • General contact in Abaqus/Standard now supports the small-sliding tracking approach to efficiently resolve contact. You can specify the small-sliding tracking approach over the entire general contact domain or over portions of the general contact domain
    • In Abaqus/Standard you can specify friction coefficients for anisotropic friction in user subroutine FRIC_COEF
    • In Abaqus you can use material names to identify regions where nondefault contact properties or surface properties are assigned in a general contact domain
    • One-dimensional pure heat transfer and coupled electrical heat elements can now be included in general contact. These elements act as master surfaces with the edge-to-surface formulation for contact interactions in pure heat transfer and coupled thermal-electrical analyses

  • Execution(Enhanced Functionality)
    • Additional command line options that improve the usability of optimization execution are now available
    • You can now read Nastran DMIG matrix data, in either text bulk data or binary Output2 format, and create an Abaqus SIM file. You can also read matrix data in an Abaqus SIM file and create a Nastran DMIG representation of that data in a text bulk data file
    • You can now create Flexible Body Interface (FBI) files in an Abaqus/Standard analysis
    • Parallel execution of element operations for models using substructures is available through SMP-based parallelization
    • In Abaqus/Explicit you can now halt the analysis, concluding the current step when a certain condition is reached and continue with the next step
