	Multiphysics Electrifies Modeling in Many Scales The Saab Group, Linköping, Sweden Flexibility was required by the Saab Group who wanted to simulate the striking of airplane wings by lightning, as well as how much the shielding material...
	COMSOL Helps Commercialize Molding Technology RocTool, Le Bourget du Lac, France Mathematical modeling is going far beyond the R&D lab and is starting to make a real difference in manufacturing processes. Today it would be virtually...
	Melt it in Mid-air EPM-Madylam Laboratory, Grenoble, France Dr. Ernst develops cold crucibles that melt incredibly hot metals and other materials without letting the melt touch the container walls. With these methods...
	A New Approach to Railgun Operation Benet Laboratories, US Army Research Engineering and Development Command, Watervliet, NY Railguns-which propel a projectile using electromagnetic forces´ promise to revolutionize projectile launchers. To adequately design them, researchers must...
	Electrical Imaging Systems Riboug Research Centre, Schlumberger, France Drilling an oil well requires a good knowledge of the subsoil. Electrical imaging provides a fuzzy picture of underground structures, which needs to be...

	A Tunable MEMS Capacitor In an electrostatically tunable parallel plate capacitor, the distance between the two plates can be modified by a spring, as the applied voltage changes. For a given voltage difference between the plates, the distance of the two...
	Cold Crucible A cold crucible is used for the manufacturing of alloys that require a high degree of purity, like titanium alloys for the aeronautic industry. The cold crucible in this model is made of several water-cooled copper sectors that form the...
	Inductive Heating of a Copper Cylinder The induced currents in a copper cylinder produce heat that in turn change the electrical conductivity. This means that the field propagation has to be solved simultaneously with the heat transfer through the cylinder and surrounding...
	Inductance of a Power Inductor Power inductors are a central part of many low-frequency power applications. They are, for example, used in the switched power supply for the motherboard and all other components in a computer. Computer simulations are necessary in the...
	Magnetic Prospecting of Iron Ore Deposits Estimating center-of-mass coordinates and the spatial extent of iron-rich layers helps decrease the cost of exploration. Magnetic prospecting is applicable for doing this for certain types of iron ore deposits. Passive magnetic...
