Abaqus 2018 is out!

The Abaqus Unified FEA suite has been updated to version 2018 and is ready for immediate download. Here's a summary of changes and improvements.

Abaqus Unified FEA is the world’s technology-leading suite of software for structural finite element modeling, solving, and visualization. The 2018 release, immediately available for download, contains

Material and element enhancements
  • The multiscale material modeling capability has been enhanced to support heat transfer, coupled temperature-displacement, linear perturbation procedures, history output of micro-level results, fiber orientations now update with large rotations and other general improved accuracy and performance
  • New user subroutines for modeling thermal materials and internal heat generation in Abaqus/Explicit
  • The linear pyramid element C3D5 and linear hybrid tetrahedron C3D4H are now available in Abaqus/Explicit
  • The three-dimensional gasket element library in Abaqus/Standard now includes temperature degrees-of-freedom.

Contact enhancements
  • General contact in Abaqus/Explicit now supports 2D and axisymmetric analysis
  • General contact in Abaqus/Standard now supports analytical rigid surfaces.
  • Initial contact stresses in Abaqus/Standard can be computed based on user-specfied stress in elements underlying the contact surface
  • New contact output variables including scalar integration of contact pressure over the surface
  • Feature edges in Abaqus/Explicit general contact update based on the current configuration facilitating efficient and accurate simulations.
  • Friction coefficients can now be specified based on the underlying surface properties and a combinatorial rule.

Linear Dynamics enhancements
  • Energy output is now supported for structural, acoustic, and coupled structural-acoustic eigenvalue procedures.
  • Temperature dependent viscous and structural damping can be specified in Abaqus/Standard
  • Performance of the complex eigensolver and brake squeal workflow has been significantly improved.
  • A hybrid CPU-GPU implementation of the steady state dynamics procedure significantly improves performance.
  • Structural energy flow, power flow and acoustic radiated energy and power can now be computed for coupled structural-acoustic steady state dynamics.

Modeling and visualization enhancements
  • Usability of the bolt loading capability in Abaqus/CAE has been significantly improved.
  • Predefined field variables can now be defined in Abaqus/CAE
  • Linear constrain equations defined in Abaqus/CAE can now include multiple nodes
  • Default element types used for meshing can be specified in the environment file
  • Free body diagrams now support composite solid elements
  • Rendering performance for the discrete element method (DEM) has been significantly improved.
  • The path plot tool now supports creating a path from a pre-defined unsorted node set.

Other key enhancements
  • Results can now be imported from multiple previous simulations.
  • Partial activation of elements can be specified during a simulation.
  • The Abaqus Scripting Interface supports multiscale material modeling commands.
  • Unsymmetric matrix input is now supported.
  • Eulerian-type inlet and outlet conditions can be specified in SPH simulations.
