Modeling Linear Motors or Generators in COMSOL Multiphysics
We demonstrate how to customize a linear periodic boundary condition to model linear motors and generators in COMSOL Multiphysics®, with an example of a tubular generator used for wave energy.
Part 2: Mapping Variables with General Extrusion Operators
Learn how to use the General Extrusion operators, which are designed to handle nonlinear mappings and the mapping of variables between geometric entities of different dimensions. Part 2 of 2.
A Thermoviscous Analysis of Acoustic Radiation Forces
Learn how to determine acoustic radiation forces, including thermoviscous and acoustophoretic effects, in the COMSOL® software.
Accessing Nonlocal Variables with Linear Extrusion Operators
In some modeling scenarios, you may need to transfer variables from one region of a computational domain (the source) to another (the destination). This can be done with an extrusion operator.
