normally, this is the usual behavior. > it seems that interior elements are really curved, is there a reason why ? > is the option Mesh.SmoothInternalEdges = 1; helping with this ? > this is new stuff indeed. curving elements that have edges or faces on a curved boundary cannot be sufficient for ensure the validity of the mesh. Some internal edges/faces may have to be curved as well.

In our computations, we assume all elements to be curvilinear. We are going to submit a paper in SISC next week about efficient assembly of high order finite element operators.
