The Korteweg-de Vries (KdV) equation models water waves. It contrasts sharply to the Burgers equation, because it introduces no dissipation and the waves travel seemingly forever. Solitons have their primary practical application in optical fibers. Specifically, a fiber’s linear ... 詳細を見る
These tutorial models show how to use the tools to assist with defining surface-to-surface radiation models. In the first model, radiation direction symbols are used to find an unexpected configuration where the opacity is not correctly defined. In the other, the topology check ... 詳細を見る
A Fabry-Perot resonator is one of the fundamental optical devices and has a broad range of applications. A few examples are that it can be used to measure length, frequency/wavelength or to filter specific spatial modes. This model uses the Beam Envelopes Interface in the bidirectional ... 詳細を見る
This example shows how to compute the critical buckling load in the presence of dead loads. A truss tower is supported by pretensioned guys. The pretension load and gravity on the truss are considered as dead loads, while the vertical load applied at the top of the tower is considered ... 詳細を見る
The thin low permittivity gap boundary condition is meant to approximate a thin layer of material with low relative permittivity compared to its surroundings. This boundary condition is available for electrostatic field modeling. This example compares the thin low permittivity gap ... 詳細を見る
This tutorial model shows how a plate-fin heat exchanger made of aluminum is used to cool down hot oil with colder air. In order to maximize heat transfer, the heat exchanger is made of a porous aluminum matrix in which the hot oil flows. Heat is conducted through aluminum fins in ... 詳細を見る
This model demonstrates the impact of convection and diffusion on the transport-limited electrodeposition of a copper microconnector bump (metal post). Microconnector bumps are used in various types of electronic applications for interconnecting components, for instance liquid crystal ... 詳細を見る
This model includes a dielectric slab waveguide with a small lossy metallic object nearby. The object causes light to be scattered, absorbed, and both reflected and transmitted along the waveguide. Learn more in this accompanying blog post: Modeling a Scatterer Near an Optical Waveguide 詳細を見る
A fuel cell unit cell is modeled using the full Butler-Volmer expression for the anodic and cathodic charge transfer reactions. The anodic and cathodic overpotentials depend on the local ionic and electronic potentials, which are obtained from the charge balance equations for ionic and ... 詳細を見る
This tutorial introduces a workflow typical of creating geometry for simulation by using Sketch mode to draw complex shapes. Follow the step-by-step instructions to draw the geometry for the analysis of a light bulb. The physics setup is described in the model Free Convection in a Light ... 詳細を見る
