Boundary respecting error

I am fairly new to Comsol and I am trying to simulate Stokes flow around a very thin (length = 2.7 um, thickness = 0.01 um) dumbbell-shaped object within a comparatively large box-shaped domain (50x50x50 um). Because of the thinness of the object, I have swept a free triangular mesh across its thickness rather than use a standard tetrahedral mesh. However, if I then try to mesh the rest of the box with a free tetrahedral mesh, I get the following error: "Failed to respect boundary element edge on geometry face...Internal error in boundary respecting." The identified face on which the meshing fails is one of the two faces corresponding to the edges of the dumbbell "neck". Would anyone know what this error means in the context of my model? (The model file is too large to attach here, but can be accessed at the following link: www.dropbox.com/s/1gj0ygdfkzk6qxm/dumbbell_CFD_creepingflow_44.mph
I have also attached two screenshots of the geometry.)
Thanks,
Matt
