Model Gallery

The Model Gallery features COMSOL Multiphysics model files from a wide variety of application areas including the electrical, mechanical, fluid, and chemical disciplines. You can download ready-to-use models and step-by-step instructions for building the model, and use these as a starting point for your own modeling work. Use the Quick Search to find models relevant to your area of expertise, and login or create a COMSOL Access account that is associated with a valid COMSOL license to download the model files.

Rotating galaxy - new

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.

Modeling trapped protons in Earth's magnetic field using an external function. - new

This model demonstrates the path of non-relativistic protons within the Earth's magnetic field. Due to the dipole nature of Earth's magnetic field, charged particles, such as electrons and protons, can get trapped in stable configurations within it for long periods of time. These configurations involve the particles rapidly bouncing from magnetic pole to magnetic pole, and drifting around the ...

Dielectrophoretic Particle Separation - new

This model demonstrates the continuous separation of platelets (PLTs) from red blood cells (RBCs) using Dielectrophoresis (DEP).
