The model utilizes a dedicated mesh refinement study, Frequency Domain RF Adaptive Mesh, which dynamically refines the mesh in the region of interest. For the Application Library model Microstrip Patch Antenna, it increases the mesh resolution around areas with high field variations. The ... En savoir plus
This example treats a pulmonary artery stenosis as a porous medium and demonstrates how to set up a model that combines free and porous media flow of a non-Newtonian fluid. The non-Newtonian behavior of blood is modeled using the Carreau model. En savoir plus
Pitting corrosion is a type of localized corrosion by which local cavities, pits, are formed on an initially smooth metal surface. A pit may be initialized by surface defects, such as an inhomogeneities in composition or shape, or mechanical abuse resulting in a small scratch or dent. ... En savoir plus
This example demonstrates how to use temperature dependent materials within the Nonlinear Structural Materials Module. A large container holds pressurized hot water. Several pipes are attached to the pressure vessel. Those pipes can rapidly transfer cold water in case of an emergency ... En savoir plus
Due to its high capacity, silicon (Si) is often added to graphite in the negative electrode of lithium-ion batteries. Silicon–graphite blended electrodes may exhibit significant thermodynamic voltage hysteresis (“path dependence”) because the equilibrium potential of the lithium–silicon ... En savoir plus
Lattice materials enable the creation of advanced additive manufacturing materials with customized mechanical properties. At the macroscopic level, these heterogeneous materials can be modeled as homogeneous materials. Homogenization techniques can accurately determine the material's ... En savoir plus
In this tutorial model, a step thrust bearing is topology optimized to maximize the bearing capacity. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be ...

In a cooling system, a microelectronic component has been identified as the critical link. Since the power is repeatedly switched on and off, the component is subjected to thermal cycling. As a results a crack grows through a solder joint and disconnects the chip from the printed circuit ... En savoir plus
This model deals with the stability of a plate with an edge crack that is subjected to a tensile load. To analyze the stability of existing cracks, fracture mechanics can be utilized. A commonly used parameter in fracture mechanics, used to predict if a specific crack will cause the ... En savoir plus
In this example, wear of the friction material in a disc brake is studied. Quasistatic friction forces are prescribed from simple kinematic considerations. The geometry of the brake pad is continuously updated to account for the material removal due to wear following the well-known ... En savoir plus
