CAD Morphing
Usually in the design cycle, the simulations and the FE modeling are carried out once the concept CAD has been generated. Due to the necessity of reducing the concept design iteration, it will be significantly critical if the concept changes are made in the FE modeling itself causing the time required for CAD generation off cycle. Morphing, as the name would suggest, is an adaptation of giving shape to a new form.
During major concept design changes, a source of major time consumption is the time taken between the CAE teams and the design department. CAD Morphing can significantly reduce the CAD data generation time since the data can be fed from available existing donor CAD Data, and the Optimized Finite Element and CFD data can be communicated to the design department directly as morphed CAD data.
DEP (Detroit Engineered Products) CAD Morphing solutions allow companies to make critical die adjustments by manipulating complex surfaces while maintaining the critical product characteristics. Concept design task involves both structural and aesthetically elegant work. To help automotive companies meet this target, the DEP (Detroit Engineered Products) provides powerful software tools in India and USA to evaluate two or more alternatives of the exterior concept design of a vehicle or product to evaluate its aesthetic appeal.
You need an original CAD model for transformation and CAE mesh with its displacement results. The morphing process associates the nodes from the mesh with the original geometry and uses the nodal displacement vectors to morph the original CAD surfaces. The usage of the original surface definitions as the starting point ensures smoothness, continuity and accuracy. Thus, it provides an accurate morphed CAD surface rather than a poor quality approximate surface fit.
The CAD Morphing allows the users across industries including automotive and aerospace in India and USA to reuse existing 3D design models, reuse existing analysis finite element meshes, create better designs faster, explore what-if scenarios for analysis without having the need for repeated CAD updates and re- meshing and explore design concepts with free form shape modification.
