Abaqus Interface 2021.1 Release Notes
Abaqus Interface
New Features
- Mechanism Browser
- Mechanism Browser support from crash profiles has been extended to the Abaqus interface. The Mechanism Browser allows for the creation of joints to transform and rotate components with respect to each other using joint types like ball joint, revolute joint, and so forth, to create desirable model configurations.
- Compound Sets
- A new set type called ‘compound’ is introduced to ensure preservation of a node and/or element set defined across main file and multiple include files upon import and export of those sets in the same order to main input file and include files.
- Analysis Procedure
- A loadstep procedure to extract complex eigenvalues and corresponding complex mode shapes has been introduced to the loadstep entity. Related keyword is *COMPLEX FREQUENCY.
Enhancements
- Grouping Materials in Entity Editor
- The Entity Editor for materials has been enhanced to group materials based on the physics.
- New Keywords
-
- *MASS FLOW RATE
- *CONTACT INITIALIZATION DATA
- *CONTACT INITIALIZATION ASSIGNMENT
- *SUPERELASTIC
- *DISCRETE SECTION
- *ELECTRICAL CONDUCTIVITY
- *MAGNETIC PERMEABILITY
- *TRANSVERSE SHEAR
- *COMPLEX FREQUENCY
- *INTERGRATED OUTPUT
- *INTERGRATED OUTPUT SECTION
- *BEAM SECTION OFFSET (under *BEAM GENERAL SECTION)
- Enhanced Keywords
-
- *BEAM SECTION, TAPER
- *NODE, NSET (Node set support at node definition)
- *DLOAD with load label TRVEC
- *CONNECTOR POTENTIAL under *CONNECTOR PLASTICITY and *CONNECTOR FRICTION
- New Element Configurations
-
- Collapsed hex heat transfer elements (first and second order) DC3D8 and DC3D20 for wedge elements.
- PD3D – Particle element for explicit analysis.
- AC3D5 and DC3D5 – New pyramid elements for acoustic and heat transfer analysis respectively
- Q3D4, Q3D6, Q3D8, Q3D10, Q3D20, and so forth – first and second order tetrahedral, and hexahedral elements with wedge elements (first order for wedges only) and their invariants for reduced integration as well as hybrids (hyperplastic) for coupled electrical-thermal-structural multiphysics analysis.
- EMC2D3 and EMC2D4 – Triangular and quadrilateral elements for electromagnetic analysis.
Resolved Issues
- Resolved an issue with MODULI option that was applicable to anisotropic hyperelasticity in conjunction with viscoelasticity.
- An issue with leakage area equal to or greater than 1 that allows lower value is resolved for *FLUID EXCHANGE ACTIVATION card.
- Node set defined on *COUPLING as surface node definition in parts and instances that failed on import has been fixed.
- Surface defined for gasket elements had duplicate elements and this issue is resolved to ensure duplicity is ignored.
- Subroutine support for *FLUID BEHAVIOR is not relevant for explicit and it is removed in explicit profile.
- An issue of reading named entities with gaps for *SURFACE SMOOTHING card is addressed.
- Empty datacards for *ELASTIC with initial definition is not allowed for Abaqus solver. This issue is resolved in HyperWorks.
