COMSOL Multiphysics has a great feature for creating 2D models from cross sections of 3D geometries. 3D models can have long solution times and take up lots of computer memory. This feature has been added to the software so that 2D models can be created from 3D symmetric or axisymmetric models to solve much quicker. They can also be created to assist in parts of a 3D model to investigate modeling strategies, as well as certain results and parameters. This video shows the simple process of creating a Work Plane in a 3D model, adding a 2D model, and using the cross section created by the Work Plane as the 2D geometry. The same materials and physics are used to run the model in 2D and the results are compared with the results from the 3D model.

COMSOL Multiphysics 具有一项非常强大的功能——基于三维几何横截面创建二维模型。三维模型不仅求解时间长,还占用大量的计算机内存,因此,软件中加入了这一功能,支持基于三维对称或轴对称模型创建二维模型,从而显著加快求解速度。此外,通过创建二维模型,还可以帮助您研究部分三维模型的建模策略,并分析特定的结果和参数。本视频演示以下操作的简单过程:在三维模型中创建“工作平面”,添加二维模型,将基于“工作平面”创建的横截面用作二维几何。本例使用相同的材料和物理场来运行二维模型,并将分析结果与三维模型结果进行比较。
