Electrodeposition on a Resistive Patterned Wafer

This example models time-dependent copper deposition on a resistive wafer in a cupplater reactor. As the deposited layer builds up, the resistive losses of the deposited layer decreases. The benefit of using a current thief for a more uniform deposit is demonstrated.

Thermal Bridges in Building Construction - 3D Structure Between Two Floors

This model studies the heat conduction in a building structure separating two floors from the external environment. Four materials with distinct thermal conductivities k compose the structure. The exterior and interior boundaries are facing environments respectively at 0°C and 20°C. The lowest temperatures on internal surfaces and the heat fluxes through each surface is compared with published ...

Beam Subjected to Traveling Load

This application simulates the transient response of a beam that is placed on several equidistant supports and is subjected to a traveling load. The purpose of the application is to analyze the response of the bridge when vehicles pass over the same. It is observed that for a bridge with given geometric and material properties, certain vehicular speeds cause resonance in the bridge and it ...

Geothermal Doublet

This is one of the two models from the blog post about heat transfer in the subsurface: https://www.comsol.de/blogs/coupling-heat-transfer-subsurface-porous-media-flow/ Note: Poroelasticity is not included here.

Pacemaker Electrode

This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in SolidWorks by using the LiveLink interface.

Electrode Growth Next to an Insulator

This example shows how to model secondary current distribution and electrode growth with a moving geometry. To avoid numerical instabilities, a seed layer is introduced in the initial geometry to obtain a right angle at the edge between the growing electrode and the insulator.

Biomechanical Model of the Human Body in a Sitting Posture

The dynamic response of a human body in any vibration environment can be predicted using this biomechanical model. In the automobile industry for instance, this model can be used in ride quality simulation and designing vibration isolators such as seats. In this example, a biomechanical model of the human body is developed to evaluate the dynamic response to the vertical vibrations in a ...

Designing a Waveguide Diplexer for the 5G Mobile Network

A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This model simulates splitting properties using a simplified 2D geometry. The computed S-parameters and electric fields at the lower and upper bands will show the diplexer characteristics in the Ka-band.

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 ...

Capacitively Coupled Plasma

This application provides insight into the instantaneous and periodic steady state solutions of a 1D capacitively coupled plasma. The geometry, pressure and applied voltage are all inputs, as is the frequency and number of RF cycles over which to solve. Aside from instantaneous and time averaged plots, global quantities for the power deposition and current are computed.
