Abaqus increases analysis power, ease of use

Abaqus Inc's Version 6.5 product suite has begun shipping. The company's analysis products, Abaqus/Standard and Abaqus/Explicit, include new developments in contact, fracture and failure analysis, and parallel computing performance. New versions of Abaqus/Standard and Abaqus/Explicit demonstrate advances in three areas: contact, fracture and failure analysis, and computing performance.

  • Abaqus/Standard provides further improvements in accuracy, performance, and robustness via such developments as new contact formulations and stabilization techniques. Abaqus/Explicit also offers several improvements in contact; eg, the ability to define initial clearances and control initial overclosures for general contact.

  • A new framework for simulating progressive failure allows Abaqus/Explicit to model damage and failure of materials, fasteners, and other connection types based on relevant criteria. New cohesive elements in Abaqus/Explicit and Abaqus/Standard can be used to model separation between two initially bonded surfaces. Modeling and visualization for fracture and failure has also been considered, as Abaqus/CAE now provides support for fracture mechanics analyses with the ability to define cracks and to create appropriate meshes. Finally, Abaqus/Standard can be used in many applications that require the modeling of wear/erosion of material at one or more surfaces.

  • New parallel element operations in Abaqus/Standard, together with the already available parallel solvers, results in complete parallelization of many Abaqus/Standard analyses and provides performance gains. Memory requirements for parallel execution of Abaqus/Explicit have been reduced, and scalar and parallel performance improvements in Abaqus/Explicit combine to reduce solution time. Distributed memory parallel execution is available with both Abaqus/Explicit and Abaqus/Standard, which lets Abaqus be run in parallel on various types of clusters.
