The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
This example is a model of a continuous casting process. Liquid metal is poured into a mold of uniform cross section. The outside of the mold is cooled and the metal solidifies as it flows through. When the metal leaves the mold, it is completely solidified on the outside, but still ... Read More
In friction stir welding, a rotating tool moves along the weld joint and melts the aluminum through the generation of friction heat. The tool’s rotation stirs the melted aluminum such that the two plates are joined. In this model, two aluminum plates are joined by generating friction ... Read More
This example demonstrates how to model a phase change and predict its impact on a heat transfer analysis. When a material changes phase, for instance from solid to liquid, energy is added to the solid. Instead of creating a temperature rise, the energy alters the material’s molecular ... Read More
This model shows how to set up a uniaxial compression test on a prestressed soil sample. Due to uniaxial compression and simple initial stress values, it is possible to determine the vertical yield stress analytically. The soil sample is modeled with soil plasticity and the Mohr–Coulomb ... Read More
This example extends the Fuel Cell Cathode tutorial to also include liquid water transport in the oxygen electrode. Liquid water is produced using a user-defined expression for vapor condensation, depending on the relative humidity level in the gas phase. An experimental capillary ... Read More
This model demonstrates the use of moving meshes in the application of copper electrodeposition on circuit boards. In these environments, the presence of cavities or 'trenches' are apparent. The model makes use of the Tertiary, Nernst-Planck interface for electrodeposition to keep track ... Read More
Tutorial model of electroplating. The model uses secondary current distribution with full Butler-Volmer kinetics for both anode and cathode. The thickness of the deposited layer at the cathode is computed as well as the pattern caused by dissolution of the anode surface. Read More
Electroless deposition or plating is a non-galvanic plating method that does not require any external electrical power. This technique is typically used for electroless plating of nickel, silver, gold and copper. In electroless deposition, partial oxidation and reduction reactions ... Read More
This model incorporates the transport and electrolytic reaction in the treatment of tumor tissue. Oxygen evolution at the anode produces protons, which lowers the pH, while chlorine production also leads to lowered pH through the hydrolysis of chlorine. One effect of a low pH is the ... Read More
Real reactors can be modeled as combinations of ideal reactors. In this example the so-called "Dead zone model" is utilized. Two ideal CSTRs with interchange are set up to model the real reactor. One CSTR represents the highly agitated region and the other the less agitated region. For ... Read More
