Structural Mechanics of Cooling Catheters
This paper describes the use of structural mechanics capabilities within COMSOL to explore new cooling catheter designs. Cooling catheters may be used to save ischemic tissue resulting from strokes or heart attacks. Typical guide catheters use metallic braiding to ensure torsional ... Read More
Time-Harmonic Modeling of Squirrel-Cage Induction Motors: A Circuit-Field Coupled Approach
Finite element modeling of three-phase induction machines requires the solution of coupled circuit and field equations. This work aims to solve this problem using a strong coupling approach. This work includes circuit field coupling and proper air-gap meshing, using the AC/DC Module of ... Read More
Finite Element Model of a Magnet Driven Reed Switch
A simple proximity sensing circuit is made using magnets actuating reed switches; these switches are wired into a larger circuit that performs auxiliary functions. The success or failure of such systems is a function of their position. A simulation using COMSOL Multiphysics is conducted ... Read More
Numerical Demonstration of Finite Element Convergence for Lagrange Elements in COMSOL Multiphysics
The convergence order of finite elements is related to the polynomial order of the basis functions used on each element, with higher order polynomials yielding better convergence orders. However, two issues can prevent this convergence order from being achieved: the lack of regularity of ... Read More
