addin point

Hi,
We are using FEFLOW 5.2, I want put add-in points on the boundary. But when i use F2 to assign the addin points, It does not accept the points Why?
When I used F2 in "continue point design it accepts.
But then in fine meshing these addinpoints on the boundary are not taken.
why?

Directly on the boundary, I'd rather use nodes in the boundary polygon than add-ins.

o.k , but it does not take all the nodes, foer e.g. i put nodes at every50m interval but it took only the nodes at 100m while meshing, why??

We have to distinguish between the nodes you have put, and intermediate nodes that are put automatically by FEFLOW. The latter ones are shown a bit smaller in editing mode, and are only used for creating curved lines. Thus only the large nodes are used for the mesh generation.
