چکیده
We detail how to use Newton's method for distortion-based curved $r$-adaption a discrete high-order metric field while matching target geometry. Specifically, we combine two terms: distortion measuring the deviation from metric; and penalty term boundary. For this combination, consider four ingredients. First, represent field, log-Euclidean interpolation on (straight-edged) mesh. Second, interpolation, first second derivatives in physical coordinates. Third, domain boundaries, propose an implicit representation 2D 3D NURBS models. Fourth, representation, obtain derivatives. The of allow minimizing objective function with method. second-order minimization, resulting meshes simultaneously match features Matching geometry using optimization is unprecedented capability $r$-adaption. This will be critical global cavity-based mesh adaption.

Order and metric geometry compatible stochastic processing
A traditional random variable X is a function that maps from a stochastic process to the real line. Here, “real line” refers to the structure (R, |⋅|, ≤) , where R is the set of real numbers, ≤ is the standard linear order relation on R , and d (x, y) ≜ |x − y| is the usual metric on R . The traditional expectation value E(X) of X is thenoften apoor choice of a statisticwhen the stochastic proc...
متن کاملA Framework for Combining State Interpolation and Partial Order Reduction
We address the problem of reasoning about interleavings in safety verification of concurrent programs. In the literature, there are two prominent techniques for pruning the search space. First, there is statebased interpolation where a collection of formulas can be generalized by taking into account the property to be verified. Second, there are tracebased methods, collectively known as “Partia...
متن کاملTopology and Geometry of Smectic Order on Compact Curved Substrates
We show that smectic order on arbitrary curved substrate can be described by differential form of rank one (1-form), whose geometric meaning is the differential of the local phase field of the density modulation. The exterior derivative of 1-form is shown to be the local dislocation density. Elastic deformations are described by superposition of exact differential forms. More importantly, we us...
متن کاملSurface Mesh Optimization, Adaption, and Untangling with High-Order Accuracy
We investigate the problem of optimizing, adapting, and untangling a surface triangulation with high-order accuracy, so that the resulting mesh has sufficient accuracy for high-order numerical methods, such as finite element methods with quadratic or cubic elements or generalized finite difference methods. We show that low-order remeshing, which may preserve the “shape” of the surface, can unde...
متن کاملSparse implicitization by interpolation: Geometric computations using matrix representations
Based on the computation of a superset of the implicit support, implicitization of a parametrically given (hyper)surface is reduced to computing the nullspace of a numeric matrix. Our approach exploits the sparseness of the given parametric equations and of the implicit polynomial. In this work, we study how this interpolation matrix can be used to reduce some key geometric predicates on the (h...
