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 demonstrates the effect of the hopper design on the resulting flow patterns of the grains exiting the hopper. The flow changes from mass flow to funnel flow when the conical angle of the hopper is increased. 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
When evaluating the efficacy of treatments for ocular diseases, modeling and simulation can be used for pharmacokinetic analysis by visualizing drug concentration and how it spreads through the eye over time. In this simplified pharmacokinetic model of a human eye, a small patch is ... Read More
Inside of a combustion chamber, the gas mix behaves as a non-gray medium. Such media require a lot of data and computational resources to get results across the whole spectrum. The Weighted Sum of Gray Gases Model (WSGG) proposes an approach to model the non-gray gas mix as a sum of ... Read More
In this model, an axial field magnetic gear with a gear ratio of 5:2 is modeled. Both the high-speed and low-speed rotors consist of permanent magnets and back iron. The low-speed rotor consists of five pole pairs, while the high-speed rotor consists of two pole pairs and the stationary ... Read More
This tutorial uses an equivalent circuit approach for modeling the performance of a lithium-ion battery, requiring no knowledge about the internal chemistry or structure of the battery. A 0D equivalent circuit battery model is defined based on a resistor connected in series with a ... Read More
Switched reluctance motors work on the principle of reluctance torque. The stator and rotor will interact to minimize the reluctance for the flux path. This application simulates the behavior of the motor when the stator winding is excited with a step voltage and when the rotor is at a ... Read More
This tutorial model demonstrates the use of the features for heat transfer in layered shells, to account for the curvature of the layers when applying heat fluxes and heat sources. The results obtained with the Heat Transfer in Shells interface applied to a boundary (with extra ... Read More
This model computes the specific acoustic radiation impedance of a very small circular vent in a flanged configuration. The model includes thermoviscous losses. The radiation impedance is fitted using a simple RL circuit which gives a simple lumped representation. The results are used ... Read More
This model demonstrates how to tune the lowest natural frequency of the diaphragm of a MEMS microphone using Shape Optimization. The Stationary then Eigenfrequency study modifies the shape of the suspension springs that support the diaphragm. Although the model is in 3D, shape change is ... Read More
