Snap Hook
This example simulates the insertion of a snap hook in its groove. Fasteners like this are common in the automotive industry, for example, in the control panel of a car. In this case it is important to know the force that must be applied in order to place the hook in the slot and also ... Read More
Spacecraft Thermal Analysis
This model demonstrates how to compute satellite temperature over multiple orbit periods by coupling Orbital Thermal Loads to Heat Transfer in Solids. The direct solar, albedo, and Earth infrared thermal loads are computed over a single orbit, and are periodically repeated over multiple ... Read More
Busbar with Surface-to-Surface Radiation
This model computes an electromagnetic-heated busbar with surface-to-surface radiation and compares the results with the busbar model without radiation. The surface emissivity of copper is varied between 0.1 (blank material), 0.3 (partially oxidized), and 0.7 (heavily oxidized). A more ... Read More
Hydrogen Diffusion in Metals
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 ... Read More
GEC CCP Reactor, Argon Chemistry
This model investigates the National Institute of Standards and Technology (NIST) Gaseous Electronics Conference (GEC) reference cell in two dimensions using the Plasma, Time Periodic interface. A 2D example helps in understanding the physics without excessive CPU time. The cell is ... Read More
Spiral Slot Antenna
A spiral slot antenna provides a conformal design and can be used for communication, sensing, tracking, positioning, and many applications in different microwave frequency bands due to its wide-band frequency response. This model shows how to build a spiral geometry using parametric ... Read More
Anechoic Coating
Anechoic coatings are used for lowering visibility to sonars, for example on submarines. This model calculates the reflection, absorption, and transmission properties of an anechoic coating on a steel plate. The calculated results from this sub-model can be used in larger system scale ... Read More
Modeling Vibration and Noise in a Gearbox: CMS Version
This example illustrates the modeling of vibration and noise in a 5-speed synchromesh gearbox of a manual transmission vehicle. A transient multibody analysis is performed to compute the gearbox vibration for the specified engine speed and external load. The normal acceleration of the ... Read More
Photonic crystal fiber blog model
This model represents index guided photonic crystal fiber as discussed in the J. D. Joannopoulus book. The dispersion diagram of the fundamental and higher order modes matches well with Chapter 9, Figure 4. The hole radius is varied from 0.23[um] to 4.69[um]. J.D. Joannopoulus, R.D. ... Read More
Operational Amplifier with Capacitive Load
An operational amplifier (op-amp) is a differential voltage amplifier with a wide range of applications in analog electronics. This tutorial models an op-amp connected to a feedback loop and a capacitive load. The op-amp is modeled as an equivalent linear subcircuit in the Electrical ... Read More
