Component Mode Synthesis with COMSOL® in 18 Minutes - Archived

Reduced-order models (ROM) can be used to simplify parts of a system using a smaller number of degrees of freedom (DOF). Linear structural components can be converted to ROMs using the Craig–Bampton method. These can be used in dynamic or stationary analyses, where ROM components can be combined with nonreduced components, which can include nonlinearities. This approach is called component mode synthesis (CMS), also known as dynamic substructuring, and can provide large improvements in terms of computing time and memory usage.

Tune into this 18-minute webinar to learn how you can use the CMS modeling approach with COMSOL Multiphysics®. We will introduce this concept using a simple, solid model of a cantilever beam as an example.
