How to delete Non-Design Spaces and merge the split geometry (dotted line)?

Non-Design Spaces can be deleted in the Model Browser. Right click on the corresponding Non-Design Space and select the “delete” option.

To merge the split cells back together a boolean merge operation can be carried out. Therefore, the picking filter needs to be set to “cells” and the Design Space as well as the former Non-Design Space cell need to be selected. After confirming the selection the geometry is complete again.
