Hi Nico, Indeed, the "old" experimental boundary layer code is really a hack: the parametric coordinates of the points are not correct; hence the failure when trying to generate high-order grids.
This is in the process of being done in the "correct way". Stay tuned... :-) Christophe On 22 Jan 2013, at 11:15, Nico Schlömer <[email protected]> wrote: > I've got a similar unwanted behavior when using a circle of which the > interior is also meshed; see attachment. > > Hints are appreciated. > > --Nico > > > On Mon, Jan 21, 2013 at 9:28 PM, Vincent, Peter E <[email protected]> > wrote: > Dear All, > > I am trying to create a 2D mesh around a circle.
