Wheel Rim Defeaturing Tutorial Series
Application ID: 88491
This tutorial series demonstrates three different approaches to remove small geometric entities from an imported 3D CAD geometry of a wheel rim: the Repair operation, the Defeaturing tools, and the Remove Details operation. Use Repair to automatically find and remove small entities within a specified tolerance, such as short edges, spikes, and slivers, or use the Defeaturing tools to detect, then select the entities to be removed. Both Repair and the Defeaturing tools modify the geometry, which can be exported after defeaturing to a 3D CAD format. Use Remove Details to automatically detect and remove small details on the finalized geometry, i.e. the geometry used for meshing, and defining materials and physics. Remove Details automatically sets up a sequence of virtual geometry operations that you can edit manually, for example to exclude entities that you would like to keep on the geometry.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
