This app demonstrates the usage of a surrogate model function for predicting the rate capability of an NMC111/graphite battery cell. The rate capability is shown in a Ragone plot. The surrogate function, a Deep Neural Network, has been fitted to a subset of the possible input data ... 詳細を見る

Diffusion-induced stress in lithium-ion battery electrode materials can occur as a result of compositional inhomogeneities during lithium intercalation in the host material particles. These stresses are important since the electrode host material can undergo significant volume changes ... 詳細を見る

This example is a benchmark problem for simulating phase change in porous media. It studies the melting process of an ice inclusion within porous media and therefore demonstrates how to couple Darcy's Law with the Heat Transfer in Porous Media interface including phase change. 詳細を見る

This example replicates the results of the Jelly Roll tutorial example using a flattened representation of the wound spiral-based geometry. See that model entry for details on the background, original geometry, materials, and the general physics setup. Mapping the original problem to a ... 詳細を見る

このアプリは, 電池テストサイクル中の NMC111/グラファイトバッテリセルのセル電圧, セル開放電圧, および内部抵抗を予測するための代理モデル関数の使用方法を示します. 代理関数 (ディープニューラルネットワーク) は, 入力データ値のサブセットに適合されています. 入力データ値は, サイクルの4つのセグメントにおける電流とバッテリセルの初期充電状態の5つを設定できます. 代理関数の評価にかかる計算コストが低いため, ノブを使用して入力値を対話的に組み合わせ, セル電圧と内部抵抗を予測できます. 値の組み合わせを選択したら, ... 詳細を見る

Lithium iron phosphate (LFP) is a common positive electrode material in lithium-ion batteries. Specific for the LFP electrode material is that its equilibrium (open circuit) potential, when defined as a function of the lithiation state, features a large flat plateau with a more or less ... 詳細を見る

A tweeter is a high frequency driver used in loudspeaker systems. An ideal tweeter will produce a constant sound pressure level at a given distance in front of the driver independently of frequency, that is, a flat response. Ideally the tweeter will also, to a certain degree, maintain ... 詳細を見る

This application demonstrates how you can access and include external thermodynamic and physical property calculations in your simulation, using the Thermodynamics feature. The example shows how you can easily modify the predefined Plug-flow reactor type in the Reaction Engineering ... 詳細を見る

This application shows how a battery cell exposed to a hybrid electric vehicle drive cycle can be investigated with the Lithium-Ion Battery interface in COMSOL. This model predicts the battery behavior to make comparisons of the monitored properties. They can be used to understand the ... 詳細を見る

This tutorial shows the analysis of a car cabin in order to study the performance of a sound system in the low to mid frequency range. The cabin is of a typical sedan interior, that is, the inside of a hard-top family car. The model studies the frequency response at the location of a ... 詳細を見る
