Problem with polygon splitting

Hi,

We are trying to split a polygon along a series of shapes prior to supermesh generation.

When inner facing borders of the shapes have been traced feflow splits the targeted polygon into the following:

Any suggestions?

It is hard to determine what went wrong from looking at the image. As a first hint: You cannot have polygons that are completely inside another polygon. If this does not help, please feel free to send your supermesh file plus necessary map files to support@dhi-wasy.de with a description of what exactly you are trying to do.
