Using parametric approach, engineers can quickly and easily create different configurations of their designs. By manipulating attributes that are interlinked, we change the features automatically– allowing designers to define entire classes of shapes, and not just specific instances. In MeshWorks, parametric designing process involves the generation of structural geometry of a project through parametric modeling techniques. Once the model is created in MeshWorks, it will automatically become parametric, so the possible structural designs can be iterated with simple changes to the bounding factors. Parametric modeler in MeshWorks ensures design optimization with minimal inputs, driving the modification and updating tasks easier & in efficient manner.
MeshWorks has a comprehensive CAE model parameterization engine with a broad range of categories of parameters that can be used at all stages of product development. Categories of parameters include: gauge, shape, sections, spot weld pitch, seam-weld-spacing, adhesive length, topology (member repositioning), features (number of holes, ribs, bulkheads, crush-initiators etc. in a given space) and general parameters. Regular FE/CFD models can be converted to intelligent parametric FE/CFD models. The parameters can be exercised as one-time execution or linked to Design of Experiments (DOE) and Multi-Disciplinary Optimization (MDO) schemes. Multiple runnable CAE models (literally hundreds of them) can be generated automatically by exercising the parametric CAE models.
Functions and Applications:
Designer using MeshWorks parametric modeler, can create any design component and parameterize them. From product design engineering perspective, some of the essential modules that are considered as design parameters in MeshWorks are:
- Shape parameter
- Structural (gauge / material) parameter
- Feature parameter
- Macro parameter
- Topology parameter
- General text parameter
Application areas includes:
- Creation of multiple holes in a given zone
- Creation of various crush initiators in a given zone
- Creation of different ribs structures in a given zone
- Automatic remeshing after design generation
- Smoothing and quality improvement after design generation
Benefits:
- Ability to do in-depth analysis for optimization studies
- Reduction in part redesign time by applying changes in geometric dimensions format
- Flexible design process with shortened engineering cycle time
- Product efficiency increased by revision that doesn’t require remodelling
- Facilitate optimization studies with different combinations of the design of a complex model
