It's very difficult to clearly understand what you're describing, it would help a lot if you would post a 3DM model file, even if it's not your exact design it would be a lot clearer if you made something of just generally similar structure to it without any specific details in it.

You can make a network surface that has a hole in the top by having one direction with open curves that touch at a bottom point, and the other direction using closed curves, like this:



But MoI may not be the right tool for your texturing job - usually to make a single NURBS surface that is closed one one end involves having the surface collapse down to a single point on that end, that's like the bottom point in the above image where the 4 vertical curves touch each other.

When using the Flow tool, the deformation will follow the structure of the surface and so where the surface's control points shrink down and collapse towards each other the deformed objects will similarly shrink down. If that is not what you need to do, then probably a CAD program like MoI is not going to be the right tool for your particular job at hand. Something that's focused more on applying organic textures on to polygon models would likely be a better fit, stuff like Modo, Cinema4D, etc...
