Example 2D mesh with periodic BC, local, unique node IDs and **FEMVertexID** (circles,ellipses) and local, unique edge IDs and their FEMEdgeIDs (trapezoid)
#### Vertex Information (VertexInfo)
The **VertexInfo** array includes the `FEMVertexID` of each local element vertex in the same order as the CGNS corners as well as the `offsetIndVertexConnect` and the `lastIndVertexConnect`
which refer to the corresponding position in the additional **VertexConnectInfo** array. Here, the `nbElemID` as well as the `localNodeID` in the corresponding `nbElemID` are saved. Therefore, the multiplicity is given as `multiplicity = lastIndVertexConnect- offsetIndVertexConnect + 1.`
