This introductory demonstration will show you the fundamental workflow of the COMSOL Multiphysics® modeling environment. We will cover all of the key modeling steps, including geometry creation, setting up physics, meshing, solving, and postprocessing.
Simulation of Adhesive Joining Processes
Advanced adhesive joining processes are inherently multiphysics in nature, involving curing of the adhesive, heat transfer through complex structures, and flow behavior that depends upon the temperature, flow rate, and degree of cure of the adhesive. I will share a model of thermocompression adhesive bonding of a silicon die to a substrate and discuss how simulation can help build an understanding of the interactions between process parameters, adhesive properties, and joint quality.
RF Tissue Ablation with Blood Flow
Radio frequency (RF) tissue ablation is a minimally invasive treatment commonly used to destroy tumors or alleviate tissue blockages. It is also a strongly coupled multiphysics problem. We will present a COMSOL Multiphysics® model that we developed for an RF tissue ablation problem targeting a tissue close to a blood vessel. We modeled the coupled electric and heat transfer fields in the tissue and blood. We accounted for blood flow, blood perfusion in the tissue, and a custom tissue damage model that we implemented as an ordinary differential equation (ODE). We will discuss the challenges in validating this model, including obtaining accurate material properties, boundary conditions, and loads.
