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.
Using the Material Libraries in COMSOL Multiphysics®
The built-in material libraries are databases with materials and their associated properties, while the add-on Material Library contains material properties for more than 3800 materials.
Verifying a HAMSTAD Benchmark for an Insulated Roof Model
Heat and moisture (HAM) transport is an important area of study for building materials and structures, as it can affect the rate and coverage area of mold growth.
Modeling Darcian and Non-Darcian Flow in Porous Media
Get an introduction to the theory behind modeling flow in porous media, including the Kozeny–Carman, Forchheimer, Ergun, Burke–Plummer, and Navier–Stokes equations.
How to Predict the Fatigue Life of Welds
After an introduction to the welding process and weld geometries, we compare the nominal stress method, notch stress method, and hot spot stress methods for predicting the fatigue life of welds.
How to Perform Lens Simulations Using the Wave Optics Module
Lens simulations in wave optics can be difficult to perform, as they usually require a lot of mesh elements. Learn how to sidestep this issue using the functionality of the Wave Optics Module.
