Magnetotellurics

Magnetotellurics is a method for estimating the resistivity profile of the Earth's subsurface using the natural electromagnetic source provided by the ionosphere. This model was defined by Zhdanov et al. in a study published in 1997. In this article, various scientific groups compared software performance on the same models. This is the model called COMMEMI-3D-2, which has become one of the ...

Quadrupole Mass Filter

A quadrupole mass filter (QMF) is a key component of a modern mass spectrometer. A QMF uses direct current (DC) and alternating current (AC) electric fields to analyze positive or negative ions by mass to charge ratio. A QMF consists of 4 parallel rods spaced equidistantly, the ratio of the rod radius to the radius of the inscribed circle is 1.148. Opposite pairs of rods are electrically ...

Rotating Galaxy

This tutorial model shows how to add customized particle-particle interaction forces. In this example the gravitational force between 2500 stars in a galaxy is modeled. The galaxy initially rotates as a rigid body, then begins to change shape due to gravitational forces.

Primary Current Distribution in a Lead-Acid Battery Grid Electrode

This 3D model example demonstrates the use of the Primary Current Distribution interface for modeling current distributions in electrochemical cells. In primary current distribution, the potential losses due to electrode kinetics and mass transport are assumed to be negligible, and ohmic losses are govern the current distribution in the cell. Here you investigate primary current distribution in ...

Truss Bridge Designer

The Truss Bridge Designer app is an example of how to design a simulation tool for a class of civil engineering structures, in this case a Pratt truss bridge. Such a bridge is characterized by the diagonal beams on each side of the bridge, which all slant down and in toward the center of the span. Because of this design, the diagonal beams are subjected only to tension, while the vertical beams, ...

Parameterized Window Preset Model

During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The international standard ISO 10077-2:2012 deals with thermal performance of windows, doors and shutters. It ...

Frame Fatigue Life

Analyzing fatigue with simulation, rather than running fatigue experiments, is a much quicker way to determine whether a certain design will fail after repeated loading and unloading. This application allows you to evaluate the fatigue life of a frame with a cutout. It is useful for understanding the concept of fatigue and how to build an equivalent app for your own designs. The Frame Fatigue ...

Doppler Shift

We have all noticed the Doppler effect when an ambulance passes by with its sirens blaring. The siren’s pitch suddenly drops the moment the ambulance starts moving away from you. Another effect you can notice is how the siren’s sound is very loud when nearby, but as soon as the ambulance has passed the sound becomes much quieter. This model simulates the acoustic Doppler effect by placing ...

Polynomial Hyperelastic Model

This model shows how you can implement a user defined hyperelastic material, using the strain density energy function. The model used is a general Mooney-Rivlin hyperelastic material model defined by a polynomial. In this example, you will see two material models based on the defined expression: a two-term equation and a five-term equation. The two-term Mooney-Rivlin material model ...

Mixer with Free Surface and Bottom Impeller

Time-dependent rotating machinery k-epsilon turbulence model of a mixer, including free surface deformation. The model equations are first solved for a frozen rotor study. The solution from the frozen rotor study is used as initial condition for the time-dependent studies, which include the displacement of the impeller. Two possible time dependent studies are available for two different rotating ...
