我指的是论文Virtual Node Algorithm for Changing Mesh Topology During Simulation。
我对此有一个非常基本的问题。node one ring本文中使用了A。我对它指的是什么感到困惑。
使用它的上下文是：
For each distinct scoop cut out of a node’s one ring, a virtual copy of the
central node is created and donated to the nodes within the given scoop
to give the mesh the degrees of freedom needed to break apart.
请帮助理解相同。
