PLM Software Parasolid V23
October 21, 2010
Parasolid has extended its support formulti-core processor hardware and is now fully thread-safe, enablingapplications to have several threads running on different processors, with eachcalling any Parasolid function simultaneously. This ispossible due to optimized thread, session, and memory management as well aserror reporting capabilities in Parasolid V23 that free the applicationdeveloper from the need to coordinate the multi-thread function calls. As aresult, applications based on Parasolid can benefit from multi-core processingspeed with less time spent in application development.
A new face deformationoperation enables highly sophisticated shape changes to digital models based oneither design requirements or simulations of shape changes that occur due toreal-world situations such as deflection under load or distortion duringtemperature cycles. Any set of faces in a model can be selected for deformationas defined by a mathematical function provided by the application. This newcapability is particularly powerful because the deformation preserves andadjusts existing features, such as offsets and blends, and the deformation mayalso be applied simultaneously with other model edits.
In response to the needsof product designers who need to create and modify complex geometry withmaximum productivity and flexibility, Parasolid V23 introduces more sophisticatedblending techniques and controls that extend the software's already impressiverange of blending capabilities into the domain of complex modeling.
Newoptions are now available to provide more refined control over the shape ofchord width blends - blends that create a uniform, aesthetically pleasing shapeand are particularly useful when working with high-quality curved surfaces.Variable chord width face blends provide new methods of defining the chordwidth and ratio of face blends as being constant or variable according toapplication-provided functions. Chord width face blends, both constant andvariable, are also enhanced with the ability to now have disc cross sections inaddition to existing rolling ball cross sections.
EdgeBlends can now be defined to be trimmed (i.e. terminated) at a specific edge orface, providing more immediate, localized and robust control of complex blendinteractions.
As the geometric modeling component - or kernel - of choicein many of the world's leading CAD, CAM and CAE applications, Parasolid isoften required to work with imported data from other systems that requirevarious levels of geometry and topology repair. ParasolidV23 includes several new functions to enhance data import and repair:
A new function enables Parasolid to analyze the topological structure of a model and repair ambiguities, thereby producing data that often meets the rigorous requirements of a fully consistent boundary-representation (b-rep) model, while maintaining the intent of the original data. For example, Parasolid can now detect and repair topological clashes between shells where two faces from different shells share a common edge, greatly reducing model repair time.
Parasolid can now automatically detect and repair surfaces that are ill-defined and unstable because they contain "degeneracies" which may go unnoticed in less accurate and less rigorous modelers.
A new option to the model checking function in Parasolid improves the productivity in working with imported data by automatically requesting more detailed reporting including new fault codes
Parasolid V23 includes furtherenhancements to the rapid development of neutral sheet modeling technology,targeted at the computer-aided engineering analysis (CAE) market. Performingthese operations at the kernel modeler level has significant advantages of performance,model consistency and functional robustness over implementing them at theapplication level. New Parasolid functions are provided for detectingand optionally repairing overlapping neutral faces - even those that may occurin apparently simple configurations - in a fraction of the time it would taketo perform this task manually. Neutral sheet faces may now also be sharedbetween more than one pair of model faces for improved performance and reducedmodel size.
New controls have been addedto the sweeping operation and restrictions have been removed to make it quickerand easier to achieve the desired shape in a single operation. A sweep can nowbe locked to face normals where the sweep path lies on a set of faces.Continuity restrictions on sweep paths have been lifted to allow visibly smoothpaths where guides, multiple profiles, scale, or twist laws are also supplied.Sweeps can now also be performed between multiple profiles, each havingmultiple loops to create disjoint bodies.
