Hello Foamers,
I've seemingly a simply problem but whatever I try I fail to solve it. I fail a create prism layers however simple the geometry is. To start with I've a a plane surface with a small hump and I want to create prsims on this surface. I'm generating a perfect volume mesh without the layers(at the boundary I just have steps). the following the error message. It would be great if anyone could provide some insight.
Cheers,

Hi Foamers

I am also facing the similar problem when running the snappyHexMesh. Can someone point out where and how to define the normal vector for the patches ?

Thanks in advance
