Modelling Joule heating with COMSOL Multiphysics (Radiofrequency ablation treatment)

This video presents the steps to model radiofrequency ablation (RFA) using COMSOL Multiphysics. Although the tissue is modelled in 2D axisymmetry, the steps presented here can be applied to problems in other dimensions. Learning objectives of this video: Piecewise functions in COMSOL Multiphysics Modelling thermal effects due to phase change Temperature dependent material properties Set up heat sources Time dependent simulations For details on the theory of RFA and the values of the material properties adopted here, please check out the papers here: https://www.sciencedirect.com/science/article/abs/pii/S0010482519300034 https://www.sciencedirect.com/science/article/abs/pii/S0307904X19306092
