Error when creating prismatic layer in ICEM

Andrew

I am trying to grow a prismatic boundary layer in ICEM, but consistently get the error "shells 89371 and 105924 not consistently oriented Application is finished Error: Prism mesher failed to create mesh"

I have tried various methods of getting round it (for example only meshing certain surfaces, meshing surfaces one at a time but the error keeps reoccuring whichever surface I try and create the layer from.

If anybody has any pointers as to how I can get the mesh to 'grow' it would be hugely appreciated!

Many thanks,

Andrew
