A distributed Bragg reflector (DBR) is a periodic structure formed from alternating dielectric layers that can be used to achieve nearly total reflection within a range of frequencies. The main advantage of DBRs over ordinary metallic mirrors is that DBRs can be engineered to have custom ... En savoir plus
This model simulates the initiation of streamers from suspended metal particles, their propagation under a high electric field, and their subsequent merging. The discharge current flows into the metal particles, which are maintained at equal potential. These suspended particles enhance ... En savoir plus
This model demonstrates one way of using equation-based modeling for generative design by using the powerful mathematical expression capabilities of COMSOL Multiphysics®. En savoir plus
This model demonstrates the ability to simulate Multibody Dynamics in COMSOL. It comprises a multilink mechanism that is used in an antique automobile as a gearshift lever. It was created out of curiosity to find out how large forces are on the individual components. The model uses ... En savoir plus
These examples demonstrate how to use a job sequence to perform a programmatic sequence of operations, including solving; saving the model to file; and generating and exporting plot groups, results, and images. In the blog post associated with these files, "How to Use Job Sequences to ... En savoir plus
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 ... En savoir plus
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. En savoir plus
In applications where pressure waves and elastic waves propagate in porous materials filled with air both thermal and viscous losses are important. This is typically the case in insulation materials for room acoustics or lining materials in car cabins. Another example is porous materials ... En savoir plus
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. En savoir plus
This small tutorial model studies energy conservation in a small conceptual test setup. The model has an inlet and outlet (modeled using ports) and a Helmholtz resonator with a very narrow neck. The acoustics in the narrow neck are modeled with Thermoviscous Acoustic for a detailed ... En savoir plus
