Surface normal direction problem [Beijing water cube case]

Grasshopper
1

Hello everyone!
I am trying to recreate the Beijing water pool. So, when I add boundary surface to Voronoi cells I noticed that some of these had wrong(interior) normals. It keeps me from properly inflation with kangaroo after that. Is there any method to analyze and flip wrong direction faces?
