Hi,

Thanks John, that works perfectly!

It's probably due to the geometry having a relatively high aspect ratio, but I'm not really sure (I'm using the AC/DC module in 2D axisymmetric mode, for what it's worth).

However, I would prefer to use the advancing front mode for cases where it does not have a problem meshing the geometry. Unfortunately, when the mesher does fail, it kicks me back to the matlab prompt.
