## Intro to Corrosion Modeling for the Oil and Gas Industry

##### Fanny Littmarck | May 22, 2014

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.

Have you been looking for software that can solve the Testing Electromagnetic Analysis Methods (TEAM) Problem 7? We solved the problem with COMSOL Multiphysics and the AC/DC Module. Here are the results.

### How to Model Stresses and Strains in COMSOL Multiphysics

##### Fanny Littmarck | May 12, 2014

We have made a video tutorial for those of you who want to learn how to model stresses and strains in COMSOL Multiphysics. In under five minutes, we walk you through the modeling steps from setting up parameters and geometry to postprocessing the results. For simplicity’s sake, we use a wrench and bolt model to demo the concept.

### AMPHOS 21 on Simulating Carbon Sequestration

##### Fanny Littmarck | May 5, 2014

According to AMPHOS 21, a COMSOL Certified Consultant, one of the proposed solutions to releasing carbon dioxide (CO2) into the atmosphere is to store the CO2 in geological formations, a technique referred to as carbon dioxide sequestration. This notion led the engineers at AMPHOS 21 to study the physical and chemical processes that occur during the injection of the gas into earth’s subsurface.

### Modeling a Branch Line Coupler

##### Fanny Littmarck | March 14, 2014

Branch line couplers, a type of 90-degree or quadrature hybrid coupler, are popular because they are simple to fabricate and easy to design. They are passive devices commonly used in single-antenna transmitter systems and I/Q signal splitters/combiners. Let’s look at the basics of how this type of coupler works and some of its important design aspects.

### Happy 541st Birthday, Nicolaus Copernicus

##### Fanny Littmarck | February 19, 2014

On this day, in the year 1473, now famous astronomer Nicolaus Copernicus was born in Torun, Poland. His main contribution to science was the controversial concept of a heliocentric universe. Five hundred years later, we not only accept the sun as the center of our solar system, we even support new theories of planets orbiting two stars at once.
