Mesh Refinement for Wave Problems

Guest Kyle Koppenhoefer May 24, 2013

This week we are happy to have Kyle Koppenhoefer of AltaSim Technologies as a guest blogger. As COMSOL Certified Consultants, AltaSim can share valuable insights into using the software — today on the topic of meshing wave problems. As part of our efforts to assist COMSOL users in performing high-quality analysis, we recently used our bi-monthly email to remind users to include twelve degrees of freedom per wavelength when meshing wave problems. This article builds on our previous advice. Wave-type […]

Swept meshing is a geometry discretization technique available in COMSOL Multiphysics for specific types of geometries, including thin geometries, geometries with bends, and models with little or no variation in a specific direction. A swept mesh starts at a source boundary and sweeps along to a specified destination boundary. In previous versions of COMSOL Multiphysics, the source and destination boundaries generally needed to be specified by the user. However, in the latest release, COMSOL Multiphysics version 4.3b, the swept mesh […]

Online engineering magazines, like Design World and Desktop Engineering, are great for anyone out there interested in emerging technologies. I especially liked a few recent articles: two in Design World’s “CAE Solutions” section and one in Desktop Engineering’s simulation section, detailing a couple of major topics important to finite element analysis, or FEA. First there is meshing, the foundation of FEA software. Second, there is optimization, which is all about maximizing efficiency and improving results. The key for any production […]

Oftentimes when you are working with devices with internal fluid flow, the imported CAD design represents the vessel material. The inside is plainly void. This may leave you clueless since it is inside where you want to create a volume mesh for the flow equations. How can you solve this meshing problem in COMSOL?
