Parameterized Concrete Beam

Reinforced concrete beams are commonly used in modern construction due to their strength and durability. By simulating such beams, engineers can ensure that the resulting structures both perform well and are safe. With simulation apps, engineers of all levels of expertise can analyze and test different designs with ease. The Parameterized Concrete Beam demo app focuses on the structural ...

Kirsch Infinite Plate Problem

This model describes a static stress analysis to obtain the stress distribution in the vicinity of a small hole in an infinite plate. The model is a classic benchmark and is described in Mechanics of Material, by D. Roylance. The stress level is then compared with the theoretical values.

Shell Conduction

This model simulates a static analysis of heat conduction in a thin conductive shell. This is a benchmark model where the result is compared with a NAFEMS benchmark solution.

Motion of Trapped Protons in Earth's Magnetic Field

This model demonstrates the path of non-relativistic protons within Earth's magnetic field. Due to the dipole nature of Earth's magnetic field, charged particles, such as electrons and protons, can get trapped in stable configurations within it for long periods of time. These configurations involve the particles rapidly bouncing from magnetic pole to magnetic pole, and drifting around the ...

Caughey-Thomas Mobility

With an increase in the parallel component of the applied field, carriers can gain energies above the ambient thermal energy and be able to transfer energy gained by the field to the lattice by optical phonon emission. The latter effect leads to a saturation of the carriers mobility. The Caughey Thomas mobility model adds high field velocity scattering to an existing mobility model (or to a ...

Electrocoating of a Car Door

This example models electrocoating of paint onto a car door in a time-dependent simulation. The deposited paint is highly resistive which results in lowered local deposition rates for coated areas. A primary current distribution in combination with a film resistance model is used to describe the charge transport in the electrolyte. The model is in 3D and uses an imported CAD geometry.

Crevice Corrosion of Iron in an Acetic Acid/Sodium Acetate Solution

Mass transport limitations within thin crevices can often result in the local electrochemistry to differ significantly between the crevice opening (mouth) and end (tip), and as a result of the differences in local chemistry, corrosion may occur. This example models crevice corrosion of iron in an acetic acid/sodium acetate solution. The model reproduces the results of Walton.

Split and Recombine Mixer Benchmark

This example models a split and recombine mixer channel in which a tracer fluid is introduced and mixed by multi-lamination. Diffusion is removed from the model using an extremely low diffusion coefficient so that any numerical diffusion can be studied in the lamination interfaces. The results compare well with Glatzel et al (Ref 1.) in both the lamination patterns and total pressure drop ...

Geometric Parameter Optimization of a Tuning Fork

This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from SolidWorks via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.

Programming of a Floating Gate EEPROM Device

This model calculates the current and charge characteristics of a floating gate Electrically Erasable Programmable Read-Only Memory (EEPROM) device. A stationary study demonstrates the effects of varying the charge stored on the floating gate by computing Current-Voltage curves as a function of the control gate voltage for two different amounts of stored charge. Time dependent studies are then ...
