Viscous layers with combined thickness greater than background mesh cell crashes

I'm trying to use salome to mesh a geometry that requires very fine surface layers. Working away from the surface I'd like a geometric progression of layer thicknesses to smoothly transition to a relatively coarse background mesh. I'm going for quad-dominated, and I think that the only algorithm suitable is netgen (although I'm happy to be corrected on this if something else works better).
As far as I can tell the viscous layer node only really works when pushing in the 'bulk mesh' by less than about one mesh cell - any more and it all goes horribly wrong. I've already played with all the options I can find to no avail. Alternatively I'll happily do the layers manually then stitch together the two meshes, but I can't work out how to get a curve offset from my existing one normal to it all along. The original curve I've brought in as a large list of points then joined with a curve. If anyone could show me a way to do that it'd be equally useful. Many thanks, Mike |
