We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

你可以将Z方向用周期边界条件设置一个网格的宽度。最好在XY平面仿真,你可以将结构仿真一个组里面,然后旋转这个组到xy p平面。

一般情况很少做2D仿真,因为它意味着第三维是无限延申的。
