In this example, we want a Force acting on the middle face and a Displacement Restraint acting on the two outer faces. Use this article for reference when creating Boundary Conditions. Add an FE Volume Mesh block and insert the Volume Meshįollow this article to create an FE Model using the Material and FE Mesh from the steps above.Set the Edge Length to 3 mm and the shape to Triangles.Add a Volume Meshblock and insert the Remesh block.Add a Remesh block and insert the Mesh from CAD Body block.Add a Mesh from CAD Body block and insert the Design Region.In this example, we want an Isotropic Elastic Property with a Young's modulus of 2.1 e+11 and a Poisson's Ratio of 0.33įollow this article to create an FE Volume Mesh from the Design Space.
The center hole face, named the loaded faceįollow this article to create a material.The two outside hole faces, named the restrained faces.Create the following variables from the CAD file:.In this example, we have a rectangular prism with three holes. The TopOpt works subtractively, and not additively, therefore it needs extra material in order to run properly. Your starting part needs to have lots of excess material to enable the TopOpt to run. The workflow includes the setup of an FE model with boundary conditions, the definition of TopOpt constraints and objectives, and post-processing of TopOpt results to create a final part design. This workflow and attached file demonstrate how to use TopOpt to design a lightweight bracket with minimal structural compliance. TopOpt allows the user to design geometries that best achieve the desired objective while considering complex and multivariate design constraints. What is Topology Optimization? Topology Optimization (TopOpt) is a numerical design operation that determines the optimal shape of a part based on a set of objectives and constraints. Learn how to run a topology optimization.
