Thermal management has become a critical aspect of today’s electronic systems, which often include many high-performance circuits that dissipate large amounts of heat. Many of these components require efficient cooling to prevent overheating. Some of these components, such as processors, ... Mehr lesen
This tutorial model demonstrates the use of the multiphysics coupling feature Thermal Connection, Layered Shell, Surfaces. In this model, one layered shell is connected to heat domains by a facing boundary. The results obtained with the Heat Transfer in Shells interface are compared with ... Mehr lesen
In a MESFET, the gate forms a rectifying junction that controls the opening of the channel by varying the depletion width of the junction. In this model we simulate the response of a n-doped GaAs MESFET to different drain and gate voltages. For a n-doped material the electron ... Mehr lesen
This model shows how to model the avalanche breakdown due to the impact ionization in a Silicon Carbide diode. The current-voltage (I-V) characteristics of the device are presented as well as the electric field distribution plot. Furthermore, the carrier generation term has been computed ... Mehr lesen
When a droplet is placed on a substrate on which surface acoustic waves (SAWs) are traveling, the energy of the SAWs is transferred into the droplet to form an acoustic field. The transferred energy is attenuated and generates a streaming flow. This type of streaming enables contactless ... Mehr lesen
In this example, the dynamics of a hopping hoop is simulated. A rigid rolling ring with a point mass on the perimeter can, under certain conditions, jump up from the surface on which it is rolling. The effects of different parameters like initial velocity and friction are explored. You ... Mehr lesen
This model studies the structural deformation of an aircraft fuselage structure subjected to buckling loads. The structure is an assembly of panels and skin connected by rivets. The Fasteners feature sets up a large number of connections and computes the forces acting on each rivet. Mehr lesen
A tube connection consisting of a flange with eight prestressed bolts is subjected to a set of loads: an internal pressure, an axial force, and an external bending moment. Due to two symmetry planes, it is sufficient to only consider one quarter of the full geometry. The study ... Mehr lesen
This model computes the input impedance/admittance to an acoustic system in the frequency domain. The system here represents a typical measurement setup used for testing hearing aids and includes domains with thermoviscous boundary layer losses. The input admittance, computed in the ... Mehr lesen
This model shows how to model a simple Shockley diode— a four-layer PNPN semiconductor device. The Shockley diode is also named as thyristor. In this model, the Analytic Doping Model node is utilized to define the doping profiles for each domain. A time-dependent study is employed to ... Mehr lesen
