Software provides distributed processing for FE models.

Press Release Summary:



Incorporating Verity(TM) add-module, fe-safe(TM) v5.2 durability analysis software provides equivalent specifications, chemical compositions, heat treatments, and failure criteria for materials including steel, iron, titanium, aluminum alloys, and copper. It allows single analysis to be spread over multiple processes, gaining speed when dealing with large models or complex analyses. Using mesh-insensitive structural stress method, software calculates equivalent structural stress at the weld.

Safe Technology Announces New Release of fe-safe(TM)



Safe Technology, Sheffield, UK March 15 2006. The latest version of the durability analysis software for FE models, fe-safe(TM) 5.2, includes a number of major enhancements along with the eagerly awaited add-module, Verity.

The release of Verity in fe-safe marks the first commercial introduction of Battelle's methodology, the revolutionary new mesh-insensitive structural stress method for fatigue evaluation of welded structures

The Verity(TM) method can be applied to structural welds in thick plate, seam welds in thin sheets, and spot welds. Benefits of the methodology are that the equivalent structural stress is calculated at the weld, not at some distance from it; A single S-N curve can be used, so there is no need to 'classify' the welded joint; The method is insensitive to the mesh density and element types used in the FEA; The same S-N curve can be used for structural welds in thin and thick plate, and to seam welds, spot welds, laser welds and other weld types.

Verity(TM) has been developed in collaboration with more than a dozen leading engineering companies, Battelle's Joint Industry Project (JIP), and has been verified by correlating the results of more than 800 sets of welded joint fatigue test data. The applicability of Verity(TM) to any area of industry where the fatigue life of welded structures and components is an issue, has profound implications for product design in terms of performance, quality and cost.

Distributed Processing in fe-safe(TM) 5.2 allows a single analysis to be spread over multiple processes, gaining significant increases in speed when dealing with large models or complex analyses. fe-safe is ideally suited to distributed processing because it analyses each node separately, i.e there is no nodal interdependence to slow the analysis down. Benchmarks indicate that substantial savings in analysis time can be achieved. fe-safe automatically splits up, queues and remerges the job. Plus, once you've hit 'analyse', the client computer is free to set up the next task. Analysis-only licenses can be purchased to utilize this feature or, if you already hold multiple fe-safe licenses, there is no additional cost!

The Extended Materials Database included as standard in fe-safe now contains more materials and more data per material. In fe-safe(TM) 5.2 there are equivalent specifications, chemical compositions, heat treatments and failure criteria for close to 500 material entries including steels, irons, titaniums, aluminium alloys, coppers and more.

Visual Loading Definition is the new GUI allowing easy set up of complex loading histories. All the complex loading definitions previously requiring editing of textual .ldf files are now available at the click of a mouse.

Pre-Scanning of FEA Models is an enhancement that provides the option to pre-read an FEA model. It provides a list of what can be read from the model and the user selects appropriate data sets to be read in. This option provides another means of speeding up the analysis without compromising on accuracy.
