There is uniformly distributed self loading on the grid so I need the triangles connected to each node. After that I would be able to alculate the loaded Area for the vertices.
Eg.: for the node marked with green I need the area of the 6 connecting triangles (to calculate the yellow area which contributes to the loading of the given vertex).
I’ve also shown in the definition above how you can make the lines into a mesh using Weaverbird, since your file only included the lines. If you already have the mesh you won’t need this step.
