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.
Engineering the Flow of Light Using Photonic Crystals
Did you know that the discovery of photonic crystals in 1980 came about because of an attempt to reduce the losses in semiconductor lasers in a specific frequency range?
Recursion and Recursively Defined Geometry Objects
Broadband antennas and metamaterials are 2 fields of engineering in which recursively defined geometry objects are a useful modeling capability. Writing methods makes this task easier.
