If the geometry was precisely created in Solidworks, using the surface of one part to make the other part, the best option is to export a Parasolid from Solidworks and read the Parasolid into DesignModeler. The reason for this is that Solidworks uses the Parasolid kernel and so does DesignModeler. That means there is no translation into a new scheme such as STEP, there is merely a transfer of data.
If Shared Topology is desired in order to mesh across a common surface shared by two bodies, you must use DesignModeler or SpaceClaim to achieve this effect.
If the geometry was not created precisely, there are repair tools in SpaceClaim and DesignModeler to try to repair geometry that has problems, but the best approach is to create precise geometry.
