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/CyclicCondition),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提供的周期性边界条件包括四种类型:连续性周期边界(Continuity),指在源和目标边界上的场值相等;反对称周期边界(Antiperiodicity),源和目标边界...

Subdividing the modeling space into different geometry objects. The Form Assembly step will allow the finite element meshes in the blue domains to slide relative to the meshes in the red domains. This step will also automatically introduce identity pairs that can be used to maintain continuity of ...
The unit cell has two periodic boundary conditions (continuity) applied on the plate sides normal to the x and y directions, in solid mechanics and in the electrostatics modules, to guarantee the same electric potential and displacements along both vertical boundaries of the geometry. The terminal...
When a boundary condition is limited by a Boolean expression likeif(r < R,..., then it is more than likely that the border of the region to which it is applied will not follow the edges of the mesh elements. This will introduce discretization errors. ...

Bonded contact can be implemented using identity pairs and a continuity boundary condition. This way the displacements in all directions are continuous between the pair boundaries. In the second study, weak springs are used to suppress the initial singularity. This is a common approach. It is ...
