    • You can now replace and create patterning for model instances
    • For fluid inflator interactions, you can specify the mass fraction or molar fraction of the ideal gas mixture as a function of inflation time, and you can use amplitudes to relate the inflation time to the analysis time and to vary the mass flow rate

    • 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

    • Symmetric modeling using cohesive elements is now available in Abaqus/Standard
  • Constraints (Enhanced Functionality)
    • You can model thermal expansion of rigid bodies, kinematic couplings, BEAM MPCs, and LINK MPCs
  • 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

    • 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
