mesh file data format problem
I generate a 2d lid-driven cavity mesh. I don't understand the meaning of the last 2 node tags as shown in the "PartitionedEntities" for the curve infors(index 6 7 8 9 ).
the node info of the "6" curve is "2 7 -10 ", but the 7 and -10 nodes doesn't even lie on the same curve as shown in the picture.
