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 simulates turbulent flow around a sports car traveling at a speed of 180 km/h using Large Eddy Simulations (LES). Read More
This example models the flow in a 90-degree pipe elbow. The flow is simulated using the k-omega turbulence model. The result is compared to engineering correlations. Read More
This is a conceptual model illustrating how to couple fluid-structure interaction, heat transfer, and thermal expansion. A bimetallic strip in an air channel is heated so that it bends. After some time, an airflow with an inlet temperature which varies in time is introduced. As a ... Read More
This example demonstrate two-phase flow in a porous medium which contains a low permeable lens. The heavier phase infiltrates the porous medium, so the low permeable lens is infiltrated only when a critical saturation at the outside is reached. Read More
This example uses the Shallow Water equations to model the impact of a water wave on a column. A body of water with a height of 0.3 meters is initially contained behind a gate. At the start of the simulation, the gate is suddenly released and the body of water forms a wave moving toward ... Read More
This model simulates the flow around an inclined NACA 0012 airfoil at different angles of attack using the SST turbulence model. The results show good agreement with the experimental lift data of Ladson and the pressure data of Gregory and O’Reilly. Read More
In this benchmark model, solid particles are released in a fully developed turbulent channel flow. The particles are subjected to a drag force that includes contributions from the fluid turbulence, implemented using a Continuous Random Walk (CRW) model. Because the turbulence in the ... Read More
The flow around the Eppler 387 airfoil is computed with the SST turbulence model both with and without the transition model. The reuslts are compared with experimental values. Read More
This example illustrates multiphase flow modeling in an airlift loop reactor. The reactor is filled with water and air bubbles are injected at the bottom through two frits. Due to buoyancy, the bubbles rise, inducing a circulating motion of the liquid. The model specifically investigates ... Read More
This example demonstrates how to import and repair a surface mesh from an STL file, and to create a mesh to simulate nasal spray application inside the human upper airways. It further demonstrates how to combine the repaired mesh with the geometry of a nasal spray, then to remesh and ... Read More
