What Is Gauge Fixing? A Theoretical Introduction
Investigate the consequences of Helmholtz’s theorem when applied to Maxwell’s equations, and when using scalar and vector potentials to represent physical fields.
Modeling a Pacemaker Electrode in COMSOL Multiphysics®
What happens when the heart doesn’t pump the way it should? Pacemakers maintain the heart rate by monitoring natural electrical signals. Pacemaker electrodes are a key part of these devices.
Strategies to Counter Small Automatic Time Steps
When solving a model, you may encounter a varying time step and discretization order, or NLfail or Tfail could be greater than 0. Use these strategies to improve the efficiency of the simulation.
Now Available: Collection of COMSOL Verification and Validation Models
You can conveniently find a selection of COMSOL models that include external verification references in a single place: the COMSOL Verification and Validation Models page.
Material Characterization by Means of Simulation
Carbon-based materials, such as synthetic specialty graphites, are found in many industries, including solar, semiconductor, car manufacturing, ceramics, and metallurgy.
Simulating the Carburization and Quenching of a Steel Gear
Gears are typically carburized and quenched to improve their fatigue durability and wear resistance. Simulation can help determine how these processes affect the gear’s residual stress state.
Happy Birthday, Olga Ladyzhenskaya
Olga Ladyzhenskaya wasn’t one to shy away from a challenge. In fact, through her research, she proved the convergence of a finite difference method for the Navier–Stokes equations.
Thermal Equilibrium and Nonequilibrium Heat Transfer in Porous Media
Heat transfer in porous media can occur under thermal equilibrium, such as a rock consisting of different minerals or trapped fluids, or nonequilibrium, like a thermal energy storage (TES) unit.
