Hi good people of CFD online. I'm currently trying to create a structured mesh around a 3D Windsor body, an automotive reference model similar to the Ahmed body. While I've done a fair amount of unstructured meshing in ICEM I'm a total novice when it comes to structured meshing (as will no doubt be clear from the images below!).

The images attached show some of the problems I'm currently facing, with overlapping grids on surfaces, and areas of mesh within the body which shouldn't be there. Now i'm fairly confident these issues are due to the blocks I've used, but despite starting from scratch many many times I always end up with similar problems.

So my question: is anyone able to look at these images and provide some insight into where they think I've gone wrong, or what I should be looking to change. I appreciate it's probably not easy to make things out from these images, so I can upload the mesh files if anybody is willing to take a look.

Any feedback very gratefully received, constructive or otherwise!
