We detail how to use Newton's method for distortion-based curved $r$-adaption to a discrete high-order metric field while matching a target geometry. Specifically, we combine two terms: a distortion measuring the deviation from the target metric; and a penalty term measuring the deviation from the target boundary. For this combination, we consider...

... 7(f), and 8(d), 8(e), 8(f) show the clipped 3D meshes and the mesh boundary, respectively. We align the axes according to the ones of Figure 5. We observe that the elements lying in the anisotropic region are compressed to attain the stretching and alignment prescribed by the metric. ...

Finite elements with polynomial basis functions on the simplex with a symmetric distribution of nodes should have a unique polynomial representation. Unisolvence not only requires that the number of nodes equals the number of independent polynomials spanning a polynomial space of a given degree, but also that the Vandermonde matrix controlling thei...
