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.
Modeling and Simulation of Microfluidic Devices
Modeling and simulation are key components of the engineering development process, providing a rational, systematic method to engineer and optimize products and dramatically accelerate the development cycle over a pure intuition-driven, empirical testing approach. Modeling and simulation help to identify key parameters related to product performance (“what to try”) as well as insignificant parameters or conditions related to poor outcomes (“what not to try”). For microfluidic devices, modeling and simulation can inform the design and integration of common components such as micropumps, manifolds, and channel networks. Modeling and simulation may also be used to estimate a range of processes occurring within the fluid bulk and near cells, including shear stresses, transport of nutrients and waste, chemical reactions, heat transfer, and surface tension and wetting effects. I will discuss how an array of modeling tools such as scaling arguments, analytical formulas, and finite element simulations may be leveraged to address these microfluidic device development issues. I will also work through a few examples in detail, including modeling a microfluidic organ-on-a-chip device.
Using Multiphysics Simulation in the Study and Design of Tokamaks
Fusion is the power source of the universe and the team at the Plasma Science Fusion Center (PSFC) at MIT is working to make clean, safe, and economical energy from fusion a reality. Research at the PSFC is focused on tokamaks, which use strong magnetic fields to confine a very hot plasma and create the conditions necessary for fusion to take place. The strong magnetic fields and high temperatures seen in a tokamak create a very harsh environment for the experimental devices and structures that are placed inside. Simulations in the COMSOL® software allow us to model the magnetic fields, electromagnetic loads, heat transfer, and fluid flow of coolants in these devices, which is essential to ensure the success of a tokamak fusion reactor.
Multiphysics Simulation in Medical Devices and Bioengineering
Computational modeling and simulation helps medical device designers meet demanding performance requirements and shorten development cycles. I will discuss modeling issues specific to medical devices, including the modeling of biological materials, blood flow, electromagnetic tissue heating, and tissue damage. I will also discuss challenges related to multiphysics coupling and to the accuracy of medical device simulations. I will show several medical device simulations we developed at Veryst Engineering using the COMSOL Multiphysics® software, including RF tissue ablation (coupled thermal, electric, and flow physics), heart valves (fluid-structure interaction), and transdermal drug delivery (nonlinear species transport).
Computational Analysis of Macroscale Ultrasonic Separators
Macroscale ultrasonic separation is a new particle separation technology with various applications, such as cell clarification, cell therapy, blood-lipid separation, oil-water separation, etc. These systems use piezoelectric transducers to create standing waves in fluid-particle mixtures. Suspended particles experience acoustic radiation forces, which depend on the particles' size and acoustic contrast. The particles are separated from a fluid as they cluster, by enhanced gravity or buoyancy. Different sized particles are separated from each other as they experience different magnitudes of the acoustic radiation forces. The fluid dynamics associated with such systems is often more complicated than their microscale counterparts due to strong multiphase effects with interactions between particles, fluid, and acoustics. Computational analysis of such systems consists of two main components: fluid-particle mixture simulations to optimize the fluid path and piezoelectric simulation coupled with structural mechanics and acoustics for the selection of optimal operation frequencies and prediction of acoustic radiation forces. This talk presents computational modeling results of various aspects of the macroscale ultrasonic separators obtained using the COMSOL Multiphysics® software and highlights important insights gained into the working of such systems.
Cloud HPC Demystified: Best Practices for Executing and Managing Multiphysics Simulations and Apps in the Cloud
Advancement in multiphysics simulation and apps allows engineers to solve more complex engineering problems. Distributing the simulation work across multiple computing nodes provides both a means to solve extremely large problems and to solve multiple model configurations simultaneously. High-performance computing in the cloud offers a variety of advantages for simulation engineers, notably an instantly scalable computing resource, an integrated environment with the COMSOL Multiphysics® software and COMSOL Server™ product, and fully automated deployment tools. Imagine the engineering challenges you could solve with unlimited computing resources. This talk will discuss how simulation engineers overcome the constraints of traditional engineering resources and processes by deploying multiphysics simulations and apps in the cloud.
