Refinement at wrong stage in SnappyHexMesh

I'm doing something dumb in setting up a two phase problem, but I can't see it. The model uses a course 3D gradient mesh from blockMesh as a starting point, and then does four layers of refinement (refineMesh) in the area around the hull. For some reason the resultant shape from snappyHexMesh seems to follow a coarse outline of the model based on the initial grid rather than the refined grid.
clunky model of hull.png Suggestions would be most welcome! |

The odd messing was due to refinement being done in only two of the three axes. refineMeshDict must be set to explicitly refine each dimension, such as with this snippet:
coordinateSystem global; globalCoeffs { tan1 ( 1 0 0 ); tan2 ( 0 1 0 ); tan3 ( 0 0 1 ); } directions ( tan1 tan2 tan3 ); |
