Inconsistent grading between a Hex and a Prism?

Hi,
I am trying to create a relatively simple mesh using blockMesh in OpenFOAM V8. However, I keep running into issues when merging a prism and a hex. I ended up using (1 1 1) for grading to see if it'd work better, but it seems not. I am trying to get a uniform mesh of about 0.01 meters and am not sure how to get there when I can't even merge simple blocks. I saw that modifying the blockMeshMerge.C files to allow more spacing for merging might help (blockMesh gives "Inconsistent point locations" for axisymmetric problem), but can't find a good tutorial to modify and use it. Since blockMesh is read only, can anyone refer me to a way to create my own blockMesh that I could use, with only the blockMeshMerge.C file modified? Alternatively, here's my blockMeshDict file, in case someone can find the issue, along with a schematic of the mesh I am trying to create, with the vertices and blocks IDed. Thank you so much for any help you can provide ! Quote:

In case it can help someone else: it turns out OpenFOAM V8 blockMesh still can't use prism as input. So I converted my 3 prisms to hex as outlined in Section 5.3.5 of the User Manual and got blockMesh to work. Can visualize it in paraview as well, now I just need to work on grading and I'm on to some fun simulations!
