COMSOL Comes to China, Successful Launch Events for 4.4
Two weeks ago, I had the privilege of visiting our two new offices in China in conjunction with all-day launch events for COMSOL Multiphysics version 4.4. Both events were greatly successful; Shanghai attracted a hundred or so attendees, while Beijing received almost one hundred and fifty.
Understanding Stabilization Methods
Most numerical simulation methods (finite elements, finite volumes, and finite differences) require stabilization methods when modeling transport applications driven mainly by convection rather than diffusion. With the finite element method (FEM), stabilization means adding a small amount of artificial diffusion. This leads to more robust and faster computational performance. Here, we provide insight on the impact of stabilization on your numerical model. We also look at an alternative numerical method that is very efficient and does not require any stabilization.
Parameter Optimization with the LiveLink™ Products
The most streamlined way to find solutions for your design parameters is to use parameter optimization with the LiveLink™ products. This is helpful when you know what results you want, but you don’t know the optimal parameter values that lead to them.
Heat Transfer in Deformed Solids
In a previous blog post, we presented the applications of conjugate heat transfer involving immobile solids. The case of immobile solids simplifies the heat equation to be solved and is often a good approximation to the temperature field. Today, we will complete the description of the physics that account for thermoelastic effects of the material when heat transfer and solid mechanics are coupled.
Hyperthermic Oncology: Hyperthermia for Cancer Treatment
High temperatures can be used to destroy tumor cells, a cancer treatment known as hyperthermic oncology. Although the idea behind this treatment method has been around for some time, it wasn’t until recently that new tools and more precise delivery of heat has allowed hyperthermia to be used for cancer treatment. As hyperthermic oncology studies continue, simulation has proven a valuable tool for achieving a deeper understanding of how to deliver heat to tumors while limiting damage to healthy tissue.
How to Include Geometry Surfaces with Solution Plots
When you have solved a model, you want to visualize your results in the best way possible. Today, we will explain how to include geometry surfaces with your solution plots, by way of an RF modeling example.
Geothermal Energy: Using the Earth to Heat and Cool Buildings
The use of geothermal heat for building climatization is a cost-effective and sustainable method. In part three of our Geothermal Energy series, we will have a closer look at shallow tubing heat collectors. An accurate prediction of their thermal performance, considering both the piping layout and local thermal properties, turns out to be an appropriate job for the Pipe Flow Module.
Intro to Corrosion Modeling for the Oil and Gas Industry
If you work in the oil and gas industry dealing with offshore drilling, corrosion is your worst enemy. A corroded oil platform is a dangerous platform and it can cost you a lot — in both lives and money. To avoid such a dark fate, you need to safeguard the steel structure from corrosion via a protection system, such as the cathodic protection process shown here.
