Mixed Diffuse-Specular Radiation Benchmark

This model shows how to use the Mathematical Particle Tracing interface to simulate mixed diffuse-specular reflection between surfaces in an enclosure. This model is separated in two parts. The first part compares the heat fluxes computed by the Mathematical Particle Tracing interface with the exact solution for two identical infinitely long parallel grey plates under mixed diffuse-specular ...

Thermal Microactuator Simplified - new

This example model consists of a two-hot-arm thermal actuator made of polysilicon. The actuator is activated through thermal expansion. The temperature increase required to deform the two hot arms, and thus displace the actuator, is obtained through Joule heating (resistive heating). The greater expansion of the hot arms, compared to the cold arm, causes a bending of the actuator. The material ...

Ion Funnel

An electrodynamic ion funnel provides an efficient means of transferring ions from regions of high pressure to high vacuum. The ion funnel can couple devices which generally operate at pressures of different orders of magnitude, such as ion mobility spectrometers and mass spectrometers, allowing mixtures of ionized gases to be separated and analyzed while minimizing losses. This model ...

1D Step Bearing

This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic step bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case.

Linear Wave Retarder

Combinations of optical devices such as polarizers and wave retarders can be used to control the intensity and polarization of transmitted radiation. In this model, two linear polarizers with orthogonal transmission axes are used to reduce the intensity of a ray to zero. Then the intensity and polarization of the transmitted ray are analyzed when a quarter-wave or half-wave retarder is placed ...

Submodeling Analysis of a Shaft

This model shows how to perform a submodeling analysis in order to evaluate structural stress. Using a submodel helps to compute the results in a refined geometry detail while applying loads and constraints in the global model.

Plasmonic Wire Grating

This application computes coefficients of refraction, specular reflection, and first order diffraction as functions of the angle of incidence for a wire grating on a dielectric substrate. The incident angle of a plane wave is swept from the normal angle to the grazing angle on the grating structure. The application also shows the electric field norm plot for multiple grating periods for a ...
