Default meshing with flawed CAD geometry

How can I make mesh with a CAD geometry which has lots gaps/cracks. Spent lots of time fixing the geometry. It's very difficult to find the intersection of the sufraces. But I do not want the model changed. Is there any meshing software available.

Thanks.

Kevin

you have to use a cartesian mesher such as harpoon from ensight or viscart from cfdrc or cart3d etc...

What meshing software are you using? One trick that we use quite often in Gridgen is to create surface patch meshes that span the gaps, write those out as plot3d meshes, and then read them back in as part of the database. It can be somewhat tedious, but that's the real world of mesh generation.
