The analysis models lack accuracy and completenessFiber orientations are incorrect; not accounting for compound curvatureZone or ply shapes used in FEA are approximate; limited by the data availablePly dropoffs and other key design details are missing

The transfer of data between design and analysis is slow and manualAnalysts looking for many more cycles, faster, earlier in the processTransfer of zone and laminate specs to design done by tables, diagramsTransfer of ply shapes and fiber orientations to analysis done by drawingsLengthy paper/verbal process for design changes, analysis changes

The data exchange process is unreliable and incompleteUse of spreadsheets, verbal communications and emailsTime consumingErrors due to interpretation, inattentionDesigners and analysts feel they don’t get complete information from the other parties

The engineering process is too sequentialDelays are incurredLimits the number of iterations and changes possible

Eventually: there is a disconnect between design, stress and manufacturingWhat’s analyzed is not what’s designed and manufactured

In recent years, achieving deeper integration of composites design and analysis has become a key challenge

Need to better and faster optimize composite parts; for weight and cost reduction

Abstractions and open format data exchange is the fastest and most efficient route to powerful integration of design and analysis software

Together VISTAGY and ANSYS are actively engaged in a comprehensive integration effort

Ply and zone design; optimization and validation analysis; for multiple part types; across industries (aero, auto, wind, marine)
