Models can be used to describe chemical reactors to help solve problems and optimize processes, while saving time, money, and resources. Mathematical modeling of chemical reactors is based on fundamental conservation laws. When these laws are combined with equations based on constitutive relations, thermodynamics, and reaction kinetics, the model?s solutions are able to describe the composition, temperature, and pressure inside a chemical reactor. Kinetic and thermodynamic equations could be used to describe the diffusivity and the reaction term. In computer models, time and space can be discretized by elements to generate a numerical model with a high resolution. Models are validated to check that they are able to describe the real system. The validation can be both qualitative and quantitative. If a qualitative validation shows that the model describes the real reactor, quantitative validation can be performed based on parameter estimation.

The electrochemical etching of silicon in HF represents a versatile process that depends on many variables. The use of multiphysics simulation to investigate the impact of process variables will lead to a viable commercial process that is relevant for a range of substrate types and applications. This article is based on an article by A. Ivanov and U. Mescheder, "Dynamic Simulation of Electrochemical Etching of Silicon with lg COMSOL," presented at the COMSOL Conference 2012, October 10-12, 2012, Milan, Italy.

A team from the Cross Cancer Institute in Edmonton, Canada has found a way to combine the two systems, MRI and Linac. The first step in designing the Linac-MR was mitigating the electromagnetic interactions that take place between the linac and MR scanner, a process that requires an in-depth understanding of how one system affects the performance of the other. A linac, on the other hand, uses an RF waveguide to create an oscillating electromagnetic (EM) field that accelerates an electron beam toward a target, thereby producing the x-rays used to destroy tumor cells. The program works by taking several images per second during treatment, and then auto-contouring the images using an in-house software that determines the tumors shape and position. The accuracy of the motion-prediction software was determined using an MR tractable 'phantom' that was representative of a tumor. The Linac-MR prototype is currently undergoing its final tests, and the team is preparing the documentation required to seek governmental approval for the device to be used in clinical trials.

Modern aircraft such as the Boeing 787 Dreamliner are comprised of more than 50% carbon fibre composite requiring the addition of expanded metal foil for lightning strike protection. Researchers at Boeing are using environmental testing and simulation to verify that protective coatings on the metal foil will not fail due to thermal stress arising from a typical flight cycle.

SolidWorks Corporation has named COMSOL as one of its select Solution Partners. This program provides SolidWorks 3D CAD users with access to integrated products and services that can further boost productivity. In this case, COMSOL Multiphysics includes a feature in the CAD Import Module called the SolidWorks Live Connection, an easy-to-use bidirectional link that allows users to modify a geometry in the CAD environment and automatically transfer these changes to a linked multiphysics model based on that geometry. Just one user who enjoys great productivity gains from this link is Mark Fowler, Senior Engineer at Digital Fusion in Huntsville, Alabama. That firm's Advanced Technology Division provides a variety of engineering services to a broad base of customers in the defense and aerospace industries. “Our designs are extremely sensitive to their thermal and structural operating environments,” explains Fowler. “COMSOL provides a finite element analysis tool that allows us to study how our designs react to simulated conditions to which the hardware will be exposed. We use the SolidWorks Live Connection to interactively iterate our CAD designs based on the simulation results. This combination has allowed us to conduct studies in a short time, which helps increase our iteration rate for hardware designs.” Users first create a CAD model in SolidWorks and then initialize the connection from within COMSOL Multiphysics; in this step the connection translates the SolidWorks model into a COMSOL Multiphysics geometry. After assigning physics properties and boundary conditions, users conduct a series of studies on the model, such as heat transfer, fluid dynamics, or electromagnetic properties. When they suspect that a change in geometry could improve a model's performance, they return to SolidWorks and make an appropriate modification. They then update the COMSOL Multiphysics model to reflect the changes in the CAD model with a simple menu selection. The physics and boundary settings are saved between geometry updates, which saves a lot of time. A bidirectional link between a CAD geometry in SolidWorks (left) and the corresponding simulation in COMSOL Multiphysics (right) allows users to quickly examine the effects of changes to the geometry, which they can steer from either environment. Users can also initiate geometry changes from within COMSOL Multiphysics. To do so, they define variables, shared by both environments, that allow for parametric studies of the geometry. It is possible to automate this procedure, yet retain the underlying physics even when the geometry changes. About the COMSOL product line COMSOL Multiphysics is a scientific-software environment for the modeling and simulation of any physics-based system. It can account for multiphysics phenomena.
