An electromagnetic wave consists of a coupled oscillating electric field and magnetic field which are always perpendicular to each other. By convention, the “polarization” of electromagnetic waves refers to the direction of the electric field. In 3D geometry, arbitrary polarization is naturally defined by the prescribing the directions of all three components of the electric […]

Multiphysics Modeling of Cooled RF Ablation In previous blog posts, we have provided extensive discussion on the Use of Computational Simulation of Medical Technology[1]. To provide a specific demonstration, this blog post will focus on describing the implementation of a multiphysics simulation of a cooled RF ablation (C-RFA) device. Traditional vs Cooled RF technology Traditional

In working with our customers, AltaSim often seeks to solve an initial problem in two dimensions to save computational time. The CAD we receive from our customers is routinely in three dimensions, and our engineers need to reduce the dimensionality of the solution space. In the past, our engineers spent significant time re-creating CAD in

At virtually every step of the model creation process, you need to select and apply materials, physics boundary conditions, and other settings to your model geometry. Bookkeeping of these settings can be challenging, especially when you re dealing with large, complex geometries and multiple physics interfaces. In COMSOL Multiphysics, Selections provides a tool to organize your model
