hello all
i want to ask about the ipobo file made by blue kenue when i generate a selafin file
what does it refer to. it connects every point in the mesh with the previous point so the shape is too strange for me as there as too many lines
can anyone please help me to know what this line refers to

Hi
The ipobo object exist in each selafin file. But in fact, there is no reason to display it. In my opinion, it will be better to mask it to avoid questions like yours.
The table is just a logical indicator for each node of the mesh. The value is 1 when the node is on a boundary, 0 otherwise.
As it is a kind of vector, with as many values as the number of points, the line just show you the path of the node numbering. Start at node 1 and finish at node npoin...
