import unconnected polygons
 
2 Attachment(s)
Hi, I my purpose is to create a geometry to simulate flow in porous media. I have created a geometry in matlab starting from a vonoroi tessellation (you can see an exemple below) and I wanna import it in design modeler. The geometry is costituted by several polygons and my purpose is to mesh the space between them.
I have imported the geometry line by line using import curve this way:

........and so on

it works cose my geometry now has been imported, but now i can't find a smart way to generate the surface between the poligon. I have tried to
generate a filled rectangle surface and than subcract with the command create->boolean all the polygons but it doesn't work because it is, in a certain sense an unconnected surface and also defined by single lines, and the program doesn't like it. I'm able to subtract polygon by polygon selecting the edges from the graphic window, but having a big number of them it is not a proper way to obtain the geometry i'm looking for.

I have loaded a part of the geometry (design modeler want more than one txt because it can't import too many points in a single time).

if someone can give me a tip...

Thanks

are you planning to use ICEM to mesh this ?
