A Molten Carbonate Fuel Cell Cathode

The fuel cell presented in this example is the Molten Carbonate Fuel Cell (MCFC), a high temperature fuel cell for stationary applications. The fuel is oxidized at the anode, and can be either hydrogen or natural gas, while oxygen is reduced at the cathode together with carbon dioxide. The electrolyte is defined in the porous electrode and in the free electrolyte, while the solid phase is ...

1D Isothermal Nickel-Metal Hydride Battery

This model simulates the discharge of a Nickel-Metal Hydride (NiMH) battery using the Battery with Binary Electrolyte interface. The geometry is in one dimension and the model is isothermal. The model serves as an introduction to NiMH modeling, and can be further extended to include various side reactions.

Buoyancy–driven μPCR for DNA Amplification

Polymerase chain reaction (PCR) is one of the most effective methods in molecular biology, medical diagnostics, and biochemical engineering in amplifying a specific sequence of DNA. There has been a great interest in developing portable PCR-based lab-on-a-chip systems for point-of-care applications and one strategy that seems very promising is natural convection-based PCR. This model studies ...

Parameter Estimation for Nonideal Reactor Models

Real reactors can be modeled as combinations of ideal reactors. In this example two ideal CSTRs with interchange are used to model a real reactor with one highly agitated region and another region with less agitation. Two parameters, relating the volume and exchange rate of the two regions, need to be found by comparing the model results to experimental tracer data. Using the Parameter Estimation ...

Pinched Hemispherical Shell

This example studies the deformation of a hemispherical shell, where the loads cause significant geometric nonlinearity. The maximum deflections are more than two magnitudes larger than the thickness of the shell. The problem is a standard benchmark, used for testing shell formulations in a case which contains membrane and bending action, as well as large rigid body rotation.

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.

Evaporator

This model shows how to compute the thickness of a thermally evaporated gold film. The thickness of the deposited film is computed both on the walls of the chamber and on the sample.

Geometric Parameter Optimization of a Tuning Fork

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

Optimizing Band Dispersion in an Electroosmotic Flow Through a Curved Microchannel

This model studies the dispersion of neutral species band through curved microchannel in an Electroosmotic flow (EOF) . Using Optimization module, geometric optimization is carried out to minimize the curve-induced dispersion.The central idea is to parametrically represent the geometry by Bézier curves and these geometric parameters are further treated as optimization parameters in the ...

Connecting Shells and Solids

This tutorial model shows how to model a structure using both shells and solids, and how to create the transition between the two modeling domains. Results are compared between the shell solution and the full 3D solution, and the effects of the transition are highlighted.
