This example demonstrates how you can apply this technique using the LiveLink™ for MATLAB®. Application Library path: LiveLink_for_MATLAB/Tutorials/domain_activation_llmatlab Model definition: Assume that you want to study the heat distribution in a larger copper plate as it is heated by a...
第一步是在 GUI 中创建一个很简单的包含耦合变量或周期性边界条件的模型,运行后保存成 m 文件,用于命令行建模。下面的几个例子就是这方面的应用:elcplextr_example.m说明如何在一个矩形几何结构中运算Poisson方程,其中引入了周期性和反周期性边界条件。elcplscalar_example.m 演示了如何使用积分耦合变量来引入一个...

我们可以通过对它进行模拟分析,熟悉一下comsol的基本操作流程comsol模型库;(这是个简单的力学模拟,不涉及耦合场的模拟,当然,comsol最强大的功能是耦合场模拟,这个我们不急,先看完这个了解一下,具体的耦合场的例子推荐大家去看官方的help文档example2,这个例子也是上面的,相比官方来说,我的首先是中文比较好懂一点,然后...

In this example, the stack is interlayered with bipolar plates that carry liquid cooling fluid. The image on the left shows the repetitive unit cell used to help form the model geometry. In contrast, the pictures in the middle and on the right show the final model geometry, which is const...
This example studies in detail how to create uniform droplets in a microchannel T-junction. Setting up the model you can make use of the Laminar Two-Phase Flow, Level Set interface. The model uses the predefined wetted wall boundary condition at the solid walls, with a contact angle of 135...
