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 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
Unwanted electrical arcing poses significant risks to the reliability and safety of electrical and electronic systems. To enhance predictive capabilities and deepen understanding of arc behavior, we present a comprehensive numerical model for simulating transient arc discharge phenomena ... Read More
This model demonstrates how to simulate surface plasmon polaritons in a thin metal layer embedded in dielectric layers. It calculates the dispersion and propagation length of surface plasmon polaritons as a function of photon energy. Read More
This 2D example of a vanadium flow battery demonstrates how to couple a secondary current distribution model for an ion-exchange membrane to tertiary current distribution models for two different free electrolyte compartments of a flow battery. The Ion-Exchange Membrane boundary node ... Read More
In this tutorial model, the far-field radiation pattern of a dipole antenna is computed in a 3D model component. Then, in a separate 3D model component, a ray is released using the far-field radiation pattern to initialize the ray's intensity, polarization, and phase. Read More
This tutorial model shows how to import a 3D scanned geometry of a human head and torso and compute the head related transfer function (HRTF). The scan is imported as a .stl file and converted into a COMSOL geometry. The HRTF is computed using the reciprocity principle, locating the ... Read More
Removing halogen groups from hydrocarbons is an important reaction step in several chemical processes. One application is water purification. Other examples involve organic synthesis, where the removal of halogen groups serves as a starting point for carbon-carbon coupling reactions. ... Read More
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic slider bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. Read More
Biodegradable metallic biomaterials such as Magnesium (Mg) are gathering attention for biomedical applications due to their favorable properties. The present model simulates dissolution of a Mg stent in a blood vessel. Due to the circumferential symmetry, only one-twelfth of the actual ... Read More
A common verification problem for geotechnical problems is a shallow stratum layer of clay. In this example a vertical load is applied on the clay strata and the static response and the collapse load are studied. The clay is modeled as an elastic-perfectly plastic material and the ... Read More
