Dieses Beispiel simuliert die unterirdische Speicherung von CO2 in einem Teil der Johansen-Formation vor der Küste Norwegens. Das CO2 wird über einen Injektionsbrunnen mit einer Rate von 15 kg/s über einen Zeitraum von 25 Jahren injiziert, danach wird der Brunnen geschlossen. Das Modell ... Mehr lesen
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 ... Mehr lesen
This model demonstrates how to simulate surface plasmon polaritons in a thin metal layer embedded in dielectric layers. It calculates the dispersion and propagation length of surface plasmon polaritons as a function of photon energy. Mehr lesen
Polymerase chain reaction (PCR) is one of the most effective methods in molecular biology, medical diagnostics, and biochemical engineering in amplifying a specific sequence of DNA. There has been a great interest in developing portable PCR-based lab-on-a-chip systems for point-of-care ... Mehr lesen
This document explains how to install and run COMSOL Multiphysics® and COMSOL Server™ with Amazon Elastic Compute Cloud™ (EC2™). This requires that you have first acquired a Floating Network License (FNL) or COMSOL Server License (CSL) from COMSOL. The license manager ... Mehr lesen
An ion-sensitive field-effect transistor (ISFET) is constructed by replacing the gate contact of a MOSFET with an electrolyte of interest. The concentration of a specific ionic species in the electrolyte can be determined by measuring the change in the gate voltage due to the interaction ... Mehr lesen
An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and transient ... Mehr lesen
Predicting the noise radiation from a dynamic system gives designers insight into the behavior of moving mechanisms early in the design process. For example, consider a gearbox in which the change in the gear mesh stiffness causes vibrations. These vibrations are transmitted to the ... Mehr lesen
Sensitivity analysis is an efficient way of computing the gradient of an objective function with respect to many control variables. This example uses the pitch and yaw in the top of a truss tower as objective functions. It shows how to compute the sensitivity of these angles with respect ... Mehr lesen
Hydrogen embrittlement refers to the degradation of metal ductility due to the absorption of hydrogen. The metal becomes more brittle and thus cracks might initiate at lower stress levels. It is important to estimate hydrogen concentration and the speed at which it diffuses into the ... Mehr lesen
