ParaMatters CogniCAD Walkthrough

摘要

THIS ARTICLE REVIEWS the Paramatters CogniCAD Topology Optimization and Generative Design program from Paramatters. CogniCAD is a cloud-based application. The user uploads CAD geometry to define design space in STEP file format. The emphasis with CogniCAD optimization is that the resulting smooth geometry is directly suitable for export and use in additive manufacturing as an STL or STEP file. CogniCAD also includes stress constraints to help ensure the resultant structure has viable strength. The design study carried out for this walkthrough develops a support structure for a container and its contents, connected to the ground at four attachment points. The container and its contents are subject to two inertia load cases: vertical and lateral. Fig. 1 shows the design scenario, as displayed in CogniCAD. I have outlined the support bolts and the container to emphasize the design intent.
