However, this does not necessarily put function approximation off the table when it comes to predicting nonlinear behaviors. On the other hand, CFD can be considered as a compromise between the analytical method and experiment. Cakici (2021), have proposed a Discrete Fourier Transform (DFT) based...
(such as rock,fractures,or other mineral fillings),and learns the style from the triangular grids.By optimizing the cost function to achieve approximation to represent both the content and the style,numerical meshes can be generated and optimized.We utilize the NST to generate meshes for rough ...
The maximum entropy moment closure for the two-moment approximation of the radiative transfer equation is presented. The resulting moment equations, known as the M1 model, are solved using a finite-volume method with adaptive mesh refine... D Fan - School of Graduate Studies - Theses 被引量:...
Mesh-to-mesh data transfer methods are evaluated in terms of not only accuracy but also the cost of computing time. Interpolation is a widely used method because of its simplicity. However, it suffers from a lack of precision when Lagrange elements are considered. Projection methods, which are...

Quantities such as loads, shape, size, and finite element mesh fidelity among others undergo minor modifications during repeated optimization runs. Hence, between such runs, the objective and constraint functions are similar if not the same. In addition, the quantity that is to be optimized such ...

3.1. Isentropic Approximation Fig. 1describes thethermodynamic relationsand phenomena determining the flow. Neglecting all non-isentropic effects — such as flow separation, wall heating, viscous boundary layers — the mass flow rate can be estimated depending only on the melt temperature which is one...
A posteriori error estimate technique is constructed for heat conduction on unstructured triangular meshes; an equal distribution of error on all triangles leads to an adaptive mesh refinement procedure [1368]. The method of second moments is used for computational heat transfer [1369]. A simple ...
