surface elements for transparent_solids.dem

[Daniel J S. <dan...@ie...>]

One thing I notice when the fill is solid is that along some of the edges of the Kuen's surface example are some oddly shaped surface elements.  For example, along the orange/red edge of the surface are some elements that appear to be tiled in a direction counter to the reset of the element flow.  Is this a known effect, either in general or for this particular manifold?  Is there some cusp along that upper ridge that causes this?
