So on the symmetry plane or edge, the 在模拟计算量非常大的几何结构的时，我们可以利用循环对称来减少内存的使用，从而节省计算时间。相较于轴对称几何结构，对旋转对称几何结构的处理可能更复杂。借助COMSOL 软件附 To set up the cyclic symmetry conditions, you use the predefined functionality available in COMSOL Multiphysics within the Solid Mechanics interface under the Periodic Condition . The cyclic symmetry boundary condition presents a special but important case of Floquet periodicity, for which the unit periodicity cell is a sector of a structure that consists of a number I have talked to several people in my network recently who would like a new feature in COMSOL Multiphysics(R), so that the 'Exterior The cyclic symmetry boundary condition presents a special but important case of Floquet periodicity, for which the unit periodicity cell is a sector of a structure that consists of a number The COMSOL discussion forum covers a wide variety of simulation topics. 2 brings new and improved features as well as five new tutorial models to the Wave Optics Module. Therefore, the physical components of the Learn how cyclic symmetry can help reduce memory usage when modeling computationally taxing geometries by using a predefined boundary condition in COMSOL. Learn more. Symmetry restraints for a half or quarter model yield only symmetry modes and anti-symmetry restraints will only give the anti-symmetry modes. To set up the cyclic symmetry conditions, you use the predefined functionality available in COMSOL Multiphysics within the Solid Mechanics interface under the Periodic Condition The 2D axisymmetric implementation in COMSOL Multiphysics by default assumes independence of the azimuthal component of the displacement. They all come with extra 当处理空间或时间上具有周期性的物理问题时，采用周期性边界条件（Periodic/Cyclic Condition），可将复杂结构的模拟简化为周期单元，在不失精确度的前提下，大大降低计算量。 COMSOL provides four periodic conditions, namely Continuity, Antiperiodicity, Floquet periodicity, Cyclic symmetry. A 3D impeller with eight identical blades The cyclic symmetry boundary condition presents a special but important case of Floquet periodicity, for which the unit periodicity cell is a sector of a structure that consists of a number COMSOL Multiphysics® version 6. In this entry, you can find three practical examples highlighting how to exploit symmetries in RF or wave optics modeling. Symmetries can often greatly reduce the size of a model and hence In this article (features a video), you'll learn about using symmetry in scattering applications to improve computation. Vibrations of an Impeller Introduction This tutorial model demonstrates the use of dynamic cyclic symmetry with postprocessing on the full geometry. Browse the threads and share your ideas with the COMSOL community. Browse the threads and share your ideas with the In this article (features a video), you'll learn about using symmetry in scattering applications to improve computation. The COMSOL discussion forum covers a wide variety of simulation topics. Learn how using symmetries in a model can help your workflow and get an overview of the relevant features in COMSOL Multiphysics®. See the difference between the four periodic conditions Learn how using symmetries in a model can help your workflow and get an overview of the relevant features in COMSOL Multiphysics®. The cyclic symmetry boundary condition presents a special but important case of Floquet periodicity, for which the unit periodicity cell is a sector of a structure that consists of a number In this video you learn, (i) What is symmetry boundary condition (ii) How time requirements for simulation can be reduced more Learn how to implement symmetry in your 3D COMSOL model efficiently and simplify complex designs. You can then build a model of the symmetric portion, which can be half, a quarter, or an eighth of the full geometry, and apply the appropriate symmetry (or antisymmetry) boundary conditions. Note that while COMSOL employees may participate in the discussion forum, COMSOL ® software users who are on-subscription should submit their questions via the Symmetry Constraints In many cases symmetry of the geometry and loads can be used to your advantage in modeling.
