By optimizing the cost function to achieve approximation to represent both the content and the style, numerical meshes can be generated and optimized. We apply the NST to generate meshes for rough fractures with asperities formed in rock, a network of fractures embedded in rock, and a sand ...
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...
For a 3-D magnetostatic model, the mesh must be linear. Generate a new linear mesh. The generateMesh function creates a linear mesh by default if the model is 3-D and magnetostatic. Get model = generateMesh(model); Specify the vacuum permeability value in the SI system of units. Get...
The Levenberg–Marquardt algorithm (LMA), a well-known trust region approach for determining the minimum of a function over a range of parameters, is used in the current ANN model technique. The multilayer perceptron (MLP) structure was used in the ANN model that was created. Because of ...
s Single Equation Wall Function [66]. In this work, the boundary layer is assumed to be fully turbulent; hence, no laminar-turbulent transition model is used. A Gauss upwind Laplacian scheme is used, with linear interpolation of the diffusion term. A structured C-grid mesh defines the ...
(This implies applications where the mesh for the flow field is far from being set so fine as to seek to solve the local convection by good approximation inside the thermal boundary layer itself.) The temperature inside the solid is approximated by a smooth transcendental function with some ...
Generate the mesh that contains the source point . In[85]:= Set the point heat source with the strength using the regularized delta function . In[89]:= Define the heat transfer PDE with a point heat source and an initial temperature field . In[91]:= Solve the PDE with NDSolveValue. ...
(like in an optical fiber) and the refractive index contrasts are small, one option to save computational time is to use the slowly varying envelope approximation (SVEA), also known as the paraxial equations, which allows users to significantly increase the mesh size and thus reduce computational...
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 ...
(e.g., 3D surfaces). It reduces error better than VQ or PCA for the same storage and yields data granularity in the approximation that better suits GPU implementation. Rather than grouping arbitrarily based on blocks in an image or polygons on a mesh, CPCA adapts cluster size and shape ...
