Intro to Density-Gradient Theory for Semiconductor Device Simulation
The density-gradient theory is a computationally efficient way to include quantum confinement in the conventional drift-diffusion formulation commonly used for simulating semiconductor devices.
Simulating Radiation Effects in Semiconductor Devices
Analyzing radiation effects in semiconductor devices is an important capability for consumer electronics, medical imaging, nuclear engineering, aerospace, and a wide range of other industries.
How to Use the Platonic Solids as Geometry Parts in COMSOL®
The Platonic solids, named after Plato, are regular, convex polyhedra that consist of the tetrahedron, cube, octahedron, dodecahedron, and icosahedron.
Finding the Best Way to Make Crêpes with Fluid Dynamics Research
The recipe for the perfect crêpe calls for flour, eggs, milk, sugar, butter, and…simulation? Fluid dynamicists used simulation to solve the optimal coverage problem for crêpe making.
How to Use Solver Suggestions in Acoustics Modeling
When you model large, industry-scale acoustics, ever find it challenging to efficiently solve the problem with the hardware at hand? Enter the solver suggestions in COMSOL Multiphysics®.
The Importance of Thermal Radiation in Your Models
Conduction and convection tend to get more attention from simulation engineers, but radiation plays an important role as well. Learn how (and why) to account for thermal radiation in your models.
How to Refine and Adapt Imported Meshes
2 features for getting the most out of your imported meshes: 1. The Refine operation quickly reduces element size. 2. The Adapt operation modifies the element size via an expression.
How to Produce 3D Far-Field Plots from 2D Axisymmetric RF Models
When modeling certain resonant structures, you can get the best of both worlds: 2D axisymmetry offers efficient computations while 3D far-field plots are available for postprocessing results.
