I want to create interface between two boundaries, first,I create the model in the UG NX 6, import a curved suface with the thickness of 2mm, then I create one big cuboid use the cuboid split the curved surface,and retain the curved surface. then import the geometry into star_ccm+, there are two bodies,split the cubiod boundry by path, select the 6 faces of the cubiod, then the left surface will be the interface surfaces, select the left surfaces of the cubiod and all the curved surface's faces create "in-place interface", do mesh remesher, and,at last... error

Make sure all of the geometery is created in UG broken out the way you want it before importing via IGES or equivalent into Star CCM+. I use to have this problem as well, but when I created all of the different volumes in Catia at once and imported the entire model into Star CCM+ it worked fine for me. Hope this helps.
