In this tutorial, a filter system for a diesel engine is modeled, including a soot layer development and oxidization. The build-up of the layer is held in check by both catalytic and non-catalytic reactions, where carbon is oxidized to carbon monoxide and carbon dioxide, which in turn ... En savoir plus
This entry is a compilation of some examples from DIN EN 1991-1-2 (Actions on structures exposed to fire). Models that are included: 1. Cooling (HT) 2. Heating (HT) 3. Heat transfer through multiple layers (HT) 4. Thermal elongation (SME, thermal stress) 5. Thermal expansion (SME, HT, ... En savoir plus
This benchmark model simulates a graded heterojunction using the thermionic emission formulation for the charge transfer over the junction. It shows the additional contribution to the current density from the quantum tunneling effect across the potential barrier, using the WKB ... En savoir plus
In a polymerization reactor for polyester manufacturing, the mixing in the reactor is achieved by impinging turbulent jets of reactants onto each other. The turbulence affects the reaction kinetics and quality of the polymer linkage. Turbulent flows involving rapid reaction kinetics are ... En savoir plus
This is a benchmark model involving stick-slip friction of a ring rolling inside another ring. The displacement of the inner ring is computed and compared to the analytical result. This model also shows how to tackle friction dominated contact problem. En savoir plus
This model demonstrates how to design a beam without low Eigenfrequencies by combining the Density Model feature in the Topology Optimization interface with the Stationary Then Eigenfrequency study step. En savoir plus
This model simulates the isotropic compression of naturally structured and artificially structured clays using the Modified Structured Cam-Clay (MSCC) material model. The aim of the example is to reproduce the compression behavior given in a benchmark for four structured clays. En savoir plus
In this first half of a two-part example, a 2D model of a trench-gate IGBT is built, which will be extended to 3D in the second half. In general, it is the most efficient to start with a 2D model to make sure everything works as expected, before extending it to 3D. The Caughey&ndash ... En savoir plus
Ultrahigh Molecular Weight (UHMW) Polyethylene is a material commonly employed in knee and hip joint replacements. The “small punch test” is designed to assess mechanical properties using very small samples, such that because of their size they can directly be explanted. This example ... En savoir plus
A battery’s possible energy and power outputs are crucial to consider when deciding in which type of device it can be used. A cell with high rate capability is able to generate a considerable amount of power, that is, it suffers from little polarization (voltage loss) even at high ... En savoir plus
