Editing and Repairing Imported Meshes in COMSOL Multiphysics®
COMSOL Multiphysics® includes several operations for modifying imported surface meshes. You can create, intersect, partition, and join entities, adapt and refine mesh elements, and more.
How to Convert Point Cloud Data to Surfaces and Solids
Sometimes, the only data you have before starting an analysis project is a set of points (also known as a point cloud). Did you know that a point cloud can be converted into a model geometry?
Computing the HRTF of a Scanned Geometry of a Human Head
Designing cochlear implants, hearing aids, headphones, and other audio devices requires precise measurements of the head-related transfer function (HRTF). Simulation and geometry import can help.
How to Use the Sketch Tools in COMSOL® to Draw 2D Geometry
Did you know that you can interactively draw and edit geometry right within the Graphics window in COMSOL Multiphysics®? Learn how to use Sketch mode with step-by-step video demonstrations.
Building Roller Chain Geometries in the Multibody Dynamics Module
You can easily set up a geometry model of a roller chain, sprocket, or roller chain sprocket assembly using the built-in parametric geometry parts in the COMSOL Multiphysics Part Library.
How to Perform a Sensitivity Analysis in COMSOL Multiphysics®
How do the parameters of your design affect its performance? Understanding this relationship is a valuable part of the design process. By performing a sensitivity analysis, you can do just that.
How to Use Topology Optimization Results as Model Geometries
Oftentimes, topology optimization is not the last step in your design process. In fact, you can use the results from a topology optimization study as model geometries for your next analysis.
How to Use the Platonic Solids as Geometry Parts in COMSOL®
The Platonic solids, named after Plato, are regular, convex polyhedra that consist of the tetrahedron, cube, octahedron, dodecahedron, and icosahedron.
